I believe the only five players possibly available and worth taking as high as #21 are Manny Lawson, Mathias Kiwanuka, Jimmy Williams, Chad Jackson and Antonio Cromartie, the latter dependant on his medical information. They all are potential all-pro players. Other players, like Greenway, Carpenter or Marshall, I would trade down and lie in wait for at the bottom of rd 1 and the top of rd 2. I think Kiwanuka would become a monster with proper strength and technique training in years 2-3, and would still be an excellent situational pass rusher in year 1. I think Williams is ****y, but he is also potentially great. I think Lawson is a project like Kiwanuka. And Cromartie could be the best corner in the NFL in 3 years if he proves durable. I believe any other player, barring the unforseen dropping of a player like Michael Huff, would be a reach at #21. So I've narrowed my pool down to five: Kiwi, Lawson, Jackson, Williams and Cromartie.
