I like KW and would truly miss the slow-white-boy-reverse.....
j/k
Seriously, I think if they resurrect the running game, he's (KW) an asset as a blocker and a #2 or rotation wideout. My #1-trim-the-fat cut is on the other side of the line.
AD I view as somewhat pricey "AJ insurance". Should AJ go down, AD can fill in full time and hopefully they would not miss too much of a beat... AD is also good on special teams.... As is KW (onsides kicks).
Not sure this is the year to tinker with the wide receiver corps so I voted "keep him"...
