10 Ernie SIMS LB COLTS
He has disappointed in recent years, but Sims joins a fast-flowing Indy defensive scheme very similar to the one Detroit ran in 2006 and '07, when he had 123 (80 solo) and 134 tackles (97 solo), respectively.
1 Bernard POLLARD DB RAVENS
He topped 100 tackles the past two years in Houston, but Pollard figures to be more of a rotational player in Baltimore. He's a liability in coverage, and Ray Lewis will swallow up a lot of ballcarriers before they get to Pollard.
2 James HALL DL RAMS
Hall was a revelation in 2010 (55 tackles, 10½ sacks) at fantasy's thinnest IDP position. But age (34), middling QB hits (seven) and pressures (31) and the drafting of defensive end Robert Quinn in the first round are red flags.
3 Curtis LOFTON LB FALCONS
While the procedures were minor, surgeries on both of Lofton's knees don't bode well for a middle linebacker with already limited range.
