the thing is his route running is pretty good now as it is. he's not nearly as bad or as raw as "they" claim, not that the number of "them" is very big now.
especially when route running can be taught and practiced. he will be on another level than hunter when he adds route running to his arsenal and its actually not as bad as they claim
and with keenan allen not working out at the combine, i doubt it's very long before patterson is considered pretty much the consensus top WR. lots of people are paying more attention to his tape now than before and are noticing how good a receiver he really is.
but any receiver coming out of college is going to have a lot of room for growth...just like any player. no one is "ready" for the NFL. the good thing is we have one of the best route runners for his time as WR coach. hard to think of a better teacher for any receiver than proehl.
