- Harvin is pretty much the only proven mismatch the Vikings' have in the passing game, aside from Jerome Simpson (and he's better than Simpson). This makes him really valuable to the Vikings. As Pro Football Focus pointed out on Twitter, the Vikings' quarterbacks combined for a QB rating of 97.2 on throws to Percy last year while sporting a 70.1 and 82.9 rating overall. Harvin also caught 71.9% of the passes thrown his way last year. He's obviously the kind of player you want when you are developing a young quarterback. He's also the kind of player you want when you are developing rookie wide receivers since he'll be the focus of defense's coverage schemes.
- The Vikings only have Harvin under contract until 2013. If they handle this situation poorly, Harvin will leave when he is a free agent. That means that if they handle this situation poorly, Percy Harvin won't be a part of the next good Vikings' team. It would also mean that the next good Vikings' team is even further away because the Vikings' turned one of their assets into nothing.
- Another thing to consider is whether Harvin will even last more than two years. While he has only missed three games in the last three years, he is a small guy, listed at 5'11 and 184lbs. He also has migraine problems. This may have contributed to why he only played 58.5% of the Vikings' offensive snaps last year (the alternative explanation is that the Vikings' offensive coaching staff isn't creative enough to figure out how to use him more often, which is actually more worrisome than Harvin leaving the Vikings and *lalalalala I can't hear you*). It's very possible that the Vikings don't expect him to still be on the team in 2014, whether because he won't re-sign or because he's broken down physically. It would explain why they drafted a similar player, Jarius Wright, this year
Regardless of whether the Vikings' expect Harvin to be around after his contract expires, they need to find a way to smooth things over with him. The worst thing they can do is end up in a contract dispute with Harvin that leaves them with no option except trading him. Percy might not be a part of the next good Vikings' team, but letting him leave for nothing, or next to nothing, will only serve to prolong the time the Vikings' spend looking up at the rest of the teams in the NFC North.
