repeat after me: "I was wrong" - see much shorter than that drivel above
I have no argument about Hill being a physical specimen but the most important attributes a top WR must possess are intelligence (to be able to get separation, read coverages, run his routs properly, etc) and good hands. Some of the best WR in the business just happen to be physical specimens too, which is an extra bonus on top of everything else, but not what makes them the best at what they do.
With Hill, similarly with this years Patterson, it's his physique that separated him from the rest, not his hands or polished routes. True that Sanchez isn't exactly the best Qb in the biz but he is not that bad either and his regression over tha past 2 seasons has due mostly to lack of continuity in the OC/QB coaching department and his supporting cast on offense.
Could Hill have fared better with a top QB throwing to him in a top offense? Most likely but that doesn't mean he will ever be the player he could be because, again, he had mostly his physique to go and be judged by at the time of the 2012 draft and was a complete unknown when it came to route running abilities and overall intelligence on the field. That's what made him an unknown quantity, a risk for many teams last year and it's not by chance he dropped into the 2nd and it was the clueless O of the Jets that first pounced on him too.
