I'd take USC's WRs too but it's close. DPJ is going to be a 1st or 2nd rounder, going far before Claypool for reference. On the Fox show ~2 weeks ago Urban said he thinks DPJ will be a top 15 pick.
Many would argue Tarik Black is actually better than DPJ. Which probably isn't true but that just goes to show you that Black is also a stud if the conversation is even happening.
Then there's Nico Collins who's a 6'4", 200 LB WR that's shown he can go up and get it, and has probably out performed both of them at times during his time at Michigan.
And #8, true freshman, is making some serious plays. He's a future NFL'er, no doubt in my mind. He shows some serious speed.
Edit - #8 and Nico Collins are actually the team leaders in most WR categories. And the other two are sure fire NFL players this year.
