Mostly agree with your rankings; with the optimism bias from being a cardinals fan personally, I'd argue you could make a 1 star increase at each position, but their current rankings are also fair. I very much disagree with the 1 star ranking at special teams however, as we have a pro bowl gunner in Justin Bethel being joined by some high upside athletes in the kick coverage team and kick return game. Probably the best coverage unit in the game, which coupled with a punter who is below average (don't think he's as bad as stats show- his hangtime is rediculous, and it seems the staff went with him for this reason. I'd choose a distance leg with our coverage team, butI digress). In short, I'd say 3 stars is fair. A perfectly average special teams unit, whose only limitation really seems to be Drew Butler's distance and the uncertainty of a new long snapper (but both seem pretty reliable this far)
Indianapolis Colts: T.Y. Hilton, WR/KR, Florida International
Andrew Luck needs a receiver to throw to besides an aging Reggie Wayne and an injury-prone Austin Collie.
Denver Broncos: DeQuan Menzie, CB, Alabama
The Broncos signed Tracy Porter this offseason, but they still need help at corner.
Minnesota Vikings: Kyle Wilber, ILB, Wake Forest
The Vikings have a huge hole at inside linebacker with E.J. Henderson moving on.
Cleveland Browns: Keshawn Martin, WR, Michigan State
The Browns may spend two selections on receivers. They've shown interest in Keshawn Martin.
Tampa Bay Buccaneers: Demario Davis, OLB, Arkansas State
The Buccaneers desperately need linebacker help. Here's another player at the position.
Pick change; previously Nigel Bradham, LB
Washington Redskins: Philip Thomas, S, Syracuse
The Redskins aren't actually planning to go into the 2012 season with Brandon Meriweather and Reed Doughty at safety, are they?
Jacksonville Jaguars: Jayron Hosley, CB, Virginia Tech
I'm not saying it won't happen, but I'm getting the indication that the Jaguars won't be spending the No. 7 pick on Stephon Gilmore. They will, however, use a Round 2-4 selection on a cornerback because they have four expiring contracts at the position next spring. Derek Cox, Rashean Mathis, William Middleton and Ashton Youboty are ALL set to hit free agency in March 2013.
Pick change; previously Marvin McNutt, WR
Carolina Panthers: Bryan Anger, P, California
The Panthers don't have a punter on the roster. Round 5 is a good time to add one.
Buffalo Bills: Tank Carder, LB, TCU
The Bills need one more linebacker to join Nick Barnett and Kelvin Sheppard in their 4-3 scheme.
Miami Dolphins: Trevor Guyton, DE/DT, California
The Dolphins could use some depth up front by adding a player who can be utilized in both the 4-3 and 3-4.
Kansas City Chiefs: Dan Herron, RB, Ohio State
The Chiefs could use some running depth despite signing Peyton Hillis.
Pick change; previously Bruce Irvin, DE/OLB
Buffalo Bills: Russell Wilson, QB, Wisconsin
The Bills will probably be looking for a developmental quarterback in the middle rounds of the 2012 NFL Draft. Russell Wilson fits the system.
Oakland Raiders: Jack Crawford, DE, Penn State
The Raiders lost two pass-rushers this offseason in Kamerion Wimbley and Trevor Scott. They'll need replacements.
San Diego Chargers: T.J. Graham, WR, N.C. State
The wide receiver position can be considered a need. Malcom Floyd is entering his contract year, while Robert Meachem is far from a proven commodity.
Pick change; previously Asa Jackson, CB
Chicago Bears: Tim Fugger, DE, Vanderbilt
The Bears need some pass-rushing help across from Julius Peppers.
Pick change; previously T.J. Graham, WR
Arizona Cardinals: Malik Jackson, DE/DT, Tennessee
The Cardinals don't really have any depth behind Calais Campbell and Darnell Dockett.
Dallas Cowboys: Kheeston Randall, DE/DT, Texas
The Cowboys had the option of picking J.J. Watt at No. 9 overall in the 2011 NFL Draft. They went with Tyron Smith, who has been great thus far, but they're hurting at the defensive end position as a consequence. Kenyon Coleman should not be starting anymore.
Philadelphia Eagles: Evan Rodriguez, TE, Temple
The Eagles have a ton of picks. One might be used on a tight end to give the quarterback a bigger target in the red zone.
New York Jets: Coty Sensabaugh, CB, Clemson
The Jets need to counter the Patriots and all of their new receivers by bringing in some cornerback help. The corner position is really thin for New York; the team has nothing behind Darrelle Revis, Antonio Cromartie and Kyle Wilson because Donald Strickland is gone.
Tennessee Titans: Joe Adams, WR/KR, Arkansas
This isn't really a pressing need or anything, but the Titans could stand to bring in another weapon for Jake Locker.
Pick change; previously Tim Fugger, DE
Cincinnati Bengals: Janzen Jackson, S, McNeese State
No one should be surprised if the Bengals pick Janzen Jackson in the middle rounds. He'd fill a huge need.
Atlanta Falcons: Ben Jones, C, Georgia
More offensive line help for the Falcons. They need a successor for Todd McClure, and they've shown a lot of interest in local product Ben Jones.
Detroit Lions: Travis Lewis, OLB, Oklahoma
The Lions can stick with their "best player available" strategy with Travis Lewis.
Pick change; previously Alfonzo Dennard, CB
Pittsburgh Steelers: Greg Childs, WR, Arkansas
The Steelers could lose Mike Wallace after this season, so here's some insurance.
Cleveland Browns: Armond Armstead, DT, USC
It wouldn't hurt to add some depth behind Ahtyba Rubin and Phil Taylor.
Pick change; previously Jack Crawford, DE
Houston Texans: Akiem Hicks, NT, Canada
The Texans could use some depth on their defensive line. Wade Phillips likes smaller nose tackles.
New Orleans Saints: Jarius Wright, WR, Arkansas
The Saints lost Robert Meachem to the Chargers, so they may look at a receiver with one of their mid-round picks.
Green Bay Packers: Ronnie Hillman, RB, San Diego State
Assuming Ryan Grant doesn't return next year, the Packers will need help behind James Starks at running back.
Baltimore Ravens: Vick Ballard, RB, Mississippi State
Ricky Williams has retired, so he can now do everything he wasn't able to do during his playing career, like smoke weed and go on tours with crappy musicians. Oh wait...
San Francisco 49ers: Michael Brewster, C/G, Ohio State
Jonathan Goodwin was just a short-term solution at center. The 49ers should bring in some competition. Brewster can also play guard, so he could start in Adam Snyder's vacated spot until Goodwin is done in San Francisco.
Cincinnati Bengals: Dwight Jones, WR, North Carolina
Considering their depth issues, the Bengals could easily draft two receivers this April. Dwight Jones has character concerns, but Cincinnati won't mind that.
Cincinnati Bengals: Alfonzo Dennard, CB, Nebraska
The Bengals could draft multiple cornerbacks this April. Do I need to tell you why they'd be interested in Alfonzo Dennard?
Pick change; previously Cliff Harris, CB
Oakland Raiders: Nicolas Jean-Baptiste, NT, Baylor
The Raiders really need help at defensive tackle. Nicolas Jean-Baptiste, coincidentally, is one of the top players available.
Baltimore Ravens: Brandon Mosley, OT, Auburn
Bryant McKinnie did a decent job at left tackle this year, but he'll be 33 in September, and with his skills eroding, he can't be counted on much longer.
Indianapolis Colts: Jonathan Massaquoi, DE/OLB, Troy
The Colts need some linebacker depth for their new 3-4 defense, both on the interior and exterior.
