So it's Calvin and then Pettigrew? That's sad.
Well, it sort of 'makes sense' in that both Pettigrew and Stafford came into the league in '09, so hes had 6 years of targets thrown his way.
Outside of Tate, the Lions have never had a solid #2 guy for more than 1 year or so. Since Tate arrived, they have basically been 1A/1B type recievers, and then a HUGE drop off. Before Tate, you had about 3 or 4 guys who had OK numbers, but only Calvin produced consistently.
2014/2015:
Johnson: 275 Targets/158 Rec/2270 yards/17 TD
Tate: 264 Targets/185 Rec/2100 yards/10 TD
In fact, since Stafford/Pettigrew entered the league in 09, Tate (in 2 years) is already 3rd on Staffords list,
slightly behind Pettigrew. That should tell you how poor Mayhew was at finding a #2 receiver damn near his entire tenure as Lions GM.
2009-Present:
Johnson (6 yrs): 900/512/8140/56
Pettigrew (6 yrs): 370/230/2210/15
Tate (2 yrs): 264/185/2100/10
