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)
Mark Ingram, RB, Saints
Mark Ingram rushed for 90 yards and a touchdown on 14 carries. The Saints may attempt to get him going in these final couple of weeks.
Russell Wilson, QB, Seahawks
Add Russell Wilson if he's somehow available (someone may have dropped him after Week 14). He'll be tough to play against the 49ers, but he's not a bad option because of his rushing potential.

Leonard Hankerson, WR, Redskins
Leonard Hankerson caught two touchdowns, but he had just two receptions.

Joique Bell, RB, Lions
Joique Bell had just seven carries compared to Mikel Leshoure's 14. So much for using him more.
Dwayne Bowe, WR, Chiefs
Dwayne Bowe was just placed on injured reserve.
Larry Fitzgerald, WR, Cardinals
You're not going to use Larry Fitzgerald against the Bears or 49ers, so you can cut him if you need the roster space.
Ryan Mathews, RB, Chargers
Ryan Mathews is out for the year with a broken collarbone.
