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 Steelers need some playmakers on both sides of the ball in 2014 and beyond, and Gilbert has the most raw tools and highest upside at the cornerback position in the draft. He can also be an immediate superstar on special teams. Look what the Patriots did to the defense this past year.
Tillman reportedly is going to test free agency, and when your in a division with WR like Megatron, Jones, Cobb, Nelson and QB's like Stafford and Rodgers, you need a secondary. A safety would work if Dix falls to them, Pryor would be a reach. His physical style of play and speed is a concern.
I've moved this pick all around, from Raider's taking Boyd (stock plummeted) to the Broncos taking Skov (an admitted overdraft), I had the Skins trade here, but after free agency, the Broncos are going for it - they aren't stockpiling picks. They go for the top CB to stay across from Talib.
With the Steelers taking Mike Evans with their first pick, they will likely look to improve their CB position, S position or DL here. Lamarcus Joyner has played both CB and S and has good coverage skills. He's pretty small, but he plays bigger than he really is. He could probably challenge for a spot as a starting CB or S, whichever one the Steelers think he would fit best at.
I have the Bengals taking a DE in round 1. They could really use youth at the CB position. One prospect that might make sense is Louchiez Purifoy. Purifoy probably should've went back to school for another year. He has decent size, although he was shorter than expected at the combine. He didn't run great, but he should still be a Day 2 pick. I think a team like the Bengals who already have adequate starters in place could make sense for Purifoy.
