Can Russell Shepard be a productive NFL WR?

The Tiger fan in me wants to say yes, and even more so because I think Shepard is a great guy and a great ambassador for the university, despite the "compliance issues" of this past summer. But we're now roughly halfway through his junior year, and he has yet to really make a mark as a WR. He's definitely got elite speed, but will his size, hands and route running ability turn off some NFL teams? I keep waiting for him to have some dominant games...but will he?
