I'm thinking the "only runs 3 routes" thing is a bit overblown.
His drops however are a concern, and I can't see how anyone could deny that.
IF he had a much lower drop rate, his yardage and TDs would be higher, and I think worthy of a WR2 designation.
Then again, he has had this ankle injury, which no one can say is not a big thing for a WR.
So, if I take it all in context, he needs to stay healthy and perform better in the remaining games AND playoffs to lock down #2 next season.
I believe he is capable of that, but he has to step up and show it more consistently. If he can't, it pretty much guarantees that Beane
uses a Day 2 pick on WR. I say Day 2 with the assumption the 1st goes to OL.
