Can Jackson maintain consistency week to week?

Two defensive players debut this week on the Top 25 Big Board: Michigan's Shawn Crable and USC's Lawrence Jackson. Dropping this week are Texas wide receiver Limas Sweed and Jackson's teammate, cornerback Terrell Thomas.

Crable really started to put the whole package together last season and has even raised his performance to start 2007 despite Michigan's 1-2 start. He's tall (6-foot-4, 245 pounds), has long arms and he would project nicely as an outside linebacker in a 3-4 defense at the next level.

Similar to Crable, Jackson finished strong in 2006 and that level has carried over to this season. He's coming off a solid effort last week at Nebraska, but what I want to see is week-to-week consistency that has been lacking at times during his career.
