A couple clips from internet articles during his stint with the Vikes as Patterson's role diminished after his rookie year.
"While Patterson's snaps increased (582 vs. 446 in his rookie year), his targets dropped (from 78, to 67), and the consensus among Vikings reporters is that he struggled to grasp the nuances of Norv Turner's new offense, too often lining up in the wrong location or running the incorrect route.
"Cordarrelle is on a good track right now, OK," said Zimmer. "Now, can he sustain? Can he continue to sustain what he's doing? Because like today, I thought he had a good day. In OTAs, I thought he improved. He'll have really good days, and then he'll have some not-so-good days. Really, I think what he needs to do is just the consistency every single day and the consistency in studying, the consistency in getting extra help that he needs if he needs it, running the routes the same all the time and understanding that there's a lot of great athletes that play professional sports, and there's a lot of great athletes that don't make it in."
The way Zimmer finished frames the entire thing:
"To me, the biggest thing with him is that, does he want to be 'Flash' or does he want to be a great receiver? I'm not trying to dog him or anything, but that's really what it is."
In other words, Patterson needs to play disciplined. He needs to master the small things that are required to play receiver in this league. He needs to learn the option routes. He needs to read defenses. It takes more than just being a great athlete.
