The Seahawks have traded former starting CB Kelly Jennings (5-11, 180, a Combine 4.39-40), who had dropped to 5th or 6th on the CB depth chart, to the Browns for career Practice Squad player (all but around 4 games in 2010 of his 2 seasons) DT Clinton McDonald (6-2, 297, 4.83-40). While I like McDonald's potential, he still only has a handful of NFL tackles. I posted around 2 or 3 days ago that Jennings would be a better trade option for the panthers than giving up a 3rd or 4th round pick for Hanson, but had no idea he would go this cheap.
The CB market is drying up fast, in addition to Jennings trade, the Patriots cut CB Jonathan Wilhite (5-11 a late growth spurt? only 5-9 1/2 when drafted, 185, 4.38-40), rather than CB Darius Butler. Wilhite hasn't played well for the Patriots, so the Panthers may not be interested in him. CB Ashton Youboty (5-11, 189, 4.39-40 at 2006 Combine)was cut by the Bucs after signing him to a 2 year free agent contract a month ago. He was never more than a deep backup with the Bills, so the Panthers will probably have no interest.
