You must have missed the post on here where someone posted a list of all the WR's making 10+ Million. Probably half of them weren't as good as Fitz and got paid the same or more. Guys like Funchess, Watkins, Cooks, Shepard, Tyrell Williams, Boyd, etc... The going rate for WR is just as bad as other positions. I'd rather pay for a known commodity that wants to play here, not just for the money.
I actually think Larry is underutilized in the offense. If you were at the Detroit game where we came back to tie, Larry had multiple huge catches that just energized the team & crowd. That's what he does. If you feed him the ball, he can dominate a game just as much as years past.
