Here is a positional cross section of the analysis users have submitted in their 2014 mock drafts. In short, what is being said per key position. Who are the top 10 at this position and what is being said about them...
The Raiders go after the top guy on their draft board and a physical freak in Sammy Watkins to give their young starting QB (whomever that may be) a chance. Watkins proved in the Orange Bowl he has the potential to be Calvin Johnson good, and is just as good of a prospect at Clowney.
The Bills need more consistency from the WRs. "Flash" Goodwin has serious speed, Stevie Johnson can go off at anytime, but EJ Manual needs more help. I could see them picking up an offensive lineman here too, but Mike Evans is extremely talented, and the Bills need a big threat. This pick is not changing, unless something crazy happens on the signing front.
The 49ers plan to bring back A. Boldin, but he's a possesion WR. V. Davis is the only speed element the 49ers have and they could use another WR who can consistently get open. Latimer is not the best WR available in my opinion, but he fits what the 49ers need, which is a speedy WR who also has size to block and catch contested passes. Latimer is also getting a lot of buzz among scouts and NFL draft personnel.
