Another reason why 'Sabermetrics' haven't become quite as popular for Football as for Baseball, is that while they are absolutely useful, they are not always 100% accurate. As far as scouting CP84 goes, the Vikings clearly saw something that they liked in him. That is part of the disconnect between scouting and statistics. Neither method will guarantee 100% accuracy, but that doesn't mean that one or the other doesn't have value. It also means that just because one method identifies a player as not very good, it doesn't mean that that player can't have success. Furthermore, I highly doubt the Vikings would have given up so many picks for him if they didn't know exactly what his weaknesses were, and had a plan for overcoming them. It also should be noted that there are wide receivers that have achieved NFL success despite having low DR numbers. In fact, you all are very familiar with him Percy Harvin
Coming out of college, Harvin was billed as a multi-use player. Someone who could take a screen pass to the house, run the ball out of the backfield, and also catch passes down the field. He absolutely lived up to that billing during his time in Minnesota. While never the best route runner, his versatility and explosiveness made him one of the best, albeit unconventional, wide receivers in the game. No one will ever confuse Harvin with a traditional number 1 receiver, but you don't have to have a dominant HaSS to find success in the NFL. While I don't have the formula to calculate it, I suspect that Jerry Rice's HaSS isn't going to crack a top anything list anytime soon. Obviously, Rice is an extreme example, but the point holds. HaSS and DR are great tools, and ones that can help us identify future Elite WRs, but it isn't an all encompassing tool.
Back to Patterson
So now, we are left with a WR who is physically dominant, particularly with the ball in his hands, but relatively unaccomplished as a college receiver. Couple that with reports of his body catching, sloppy route running, and poor release, and what exactly do what have on our hands? Well, it seems that we have exactly what we thought we would have when we drafted him: a raw receiver who has tons of potential. The reason why I'm not as alarmed as some might be with Patterson's low DR is because that was his only year of playing against top college opponents. The fact that he came in as an unrefined player, and did as well as he did, is impressive to me. From all of Arif's accounts from training camp, he has slowly started to improve his route running, has been working on his release, and is decidedly not a body catcher.
I've seen people say they see a little Julio Jones in him before, which I don't think is a fair comparison to either player. While they are both physical specimens, Julio Jones is very accomplished as a route runner, and was much farther ahead of CP84 when he came out of college. That's not to say that Patterson can't get there, but he is definitely not there yet.
So, what can we expect from Patterson moving forward? Well, the Vikings will obviously attempt to get him the ball in space, and let him do his thing. People who want him to overtake Simpson this year had better hope that he picks up the finer points of being an NFL receiver quickly. As for his long term prospects, it really is a waiting game at this point. He has the physical tools to be an Elite NFL wide receiver, that much is clear. Whether he becomes that all depends on if he can pick up the finer points of the game. If he isn't able to do this, he won't necessarily be a bust, he could still find success, but it probably won't end up looking like Julio Jones' success. It will be more like
Percy Harvin's success.
