As of right now there are about a dozen guys who I have pegged as "Pats prospects", regardless of where they are likely to go in the draft - versatile, smart, high motor, physical, team-first guys (juniors with an asterix *):
1. Marcell Dareus*, DE/DT, Alabama. 6'4" 296#, nicknamed "the Beast". Top 15 pick.
2. Dont'a Hightower*, LB, Alabama. 6'4" 250#, versatile and physical. Could end up better than Rolando McClain, and could play inside or out. Coming off a knee injury, but supposedly has been tearing it up in Spring practice.
3. Akeem Ayers, OLB, UCLA. 6'4" 252#. Built like a fire hydrant but able to cover sideline to sideline.
4. Michael Floyd*, WR, Notre Dame. 6'3" 220#. A physical WR who plays like Dez Bryant, but without the issues.
5. John Moffitt, OG/C, Wisconsin. 6'5" 323#. A Connecticut kid with 29 starts through is junior year, 15 at center, 14 at LG.
6. Jason Pinkston, OT, Pittsburgh. 6'4" 305#. Very athletic and experienced OT. Former TE.
7. Jeremy Beal, DE/OLB, Oklahoma. 6'3" 263#. Versatile, high motor blue collar guy who started out at OLB.
8. Cliff Matthews, DE/OLB, South Carolina. 6'4" 249#. Very high motor guy who has played LB as well as DE for the gamecocks.
9. Daniel Thomas, RB, Kansas St. 6'2" 227#. A bruising back with soft hands who averaged 5.1 YPC and 10.3 YPR.
10. Jacquizz Rodgers*, RB, Oregon St. 5'7" 193#. A "pocket Hercules" with 22 TDs and 75 receptions last year.
11. Ryan Winterswyk, DE/OLB, Boise St. 6'4" 263#. Another versatile, high motor kid.
12, Andrew Phillips, OG, Stanford. 6'5" 300#. A classics major who was a beast last year both protecting Andrew Luck and blocking for Toby Gerhart.
There's probably some others, but these 12 seem like Pats-type players to me. I wouldn't be surprised to see at least one of them on the roster a year from now.
