Seattle Seahawks coach Pete Carroll, asked this offseason about the long list of former USC players drafted in the first round, once said he was surprised NFL teams valued some of his former players so highly.
Defensive end Lawrence Jackson comes to mind as one likely example after Seattle agreed to trade the 2008 first-round choice to the Detroit Lions. The deal will likely recoup a late-round pick after Seattle sent its own 2011 sixth-rounder to San Francisco in the Kentwan Balmer trade.
Jackson hadn't done much in training camp. A hamstring injury was keeping him off the field.
Giving up on Jackson so quickly shouldn't come as a surprise. These things happen when new coaching staffs and personnel departments take over. Carroll would know better than just about anyone whether Jackson would fit in his defense. He would have a good feel for what Jackson might become as an NFL player.
If Jackson wasn't going to fit in Seattle, the Seahawks were wise to get something in return for him -- even if it was only a sixth-round pick.
