Anything is possible, but there is little chance we re-sign Witherspoon IMO. I'd rather we not unless it's bargain cheap, so to me we will end up needing to upgrade that position which leaves it open for Kendrick/Durant/Tomlinson for the other CB spots.
And the results speak for themselves here:
7th worst in pressure % - which means it's A LOT harder on our pass coverage, right?
12th best in passer rating allowed
7th best in completion percentage allowed
6th in passing TDs allowed - and before anyone gets snarky, let's add the two PIs that Kendrick got called for against SF and PHI in the end zone that turned into rushing TDs - that takes us to 8th in passing TDs allowed
That is flat out incredible given how poor our pass rush has been. Now factor in how bad the offense has been as well - which allows teams to run the ball more and gives opposing offenses more opportunities in general.
If we fix the offense, which HAS to be the priority, followed by the pass rush - our CBs are fine. Hell, better than fine really based on the data.
So can we upgrade him? Sure. Should we? Not before LT, C, adding a WR and RB, adding a QB and an EDGE.
