Could be a great move for both sides.
I'm a huge fan of veteran Phil Stambaugh...
http://www.fwl.org.uk/alltime.htm#pstambaughBeen superb for NY.
Campbell on paper looks a great QB but a trade would be sensible, think he would do better elsewhere. Its like my HB Joe Hall, i didnt want to bench him but hes having a nightmare year, on paper hes my best HB but hes not performing so i've had to make the change (and had a decent rushing attack this week).
Stambaugh was superb last year when he was named the starter again, Campbell did alright the year before with 3,800 yards, 12 td's and 4 ints but NY didnt seem the same. Think Campbell needs a move, hope it happens.
