There is no reason that Driver cannot challenge Walker as the #1 in GB.
In his breakout year 2002 Driver had 70/1,064 and Walker 2003 had 41/716.
Driver's neck injury opened the door for Walker last year and Walker did not exactly run away to become the unquestioned #1.
Driver is healthy again, 29 is not old for a WR (Moss 27, Harrison 32, Holt 28, Owens 30 etc..) and he finished the season strong. The presence of Walker and Ferguson devalues Driver a little but he is a strong #2 receiver in a 12 team league who can be drafted in a spot where you normally draft a #3 or #4 - this means Driver is undervalued and the draft is all about value.
