Sometimes, you have to look beyond combine results with a guy. More often than not, you definitely want a guy who shows significant physical traits. So yeah, I am probably taking that LB who ran a 4.5 over the LB who ran a 4.9.
But some guys just are studs regardless of their "numbers". Treadwell appears to be that type of guy. I doubt he's ever an AJ Green or Julio Jones or even Dez. But I think he can be a very, very good WR in this league. A good comparison might be someone like Michael Floyd in Arizona. Certainly not an elite WR, but a very good one.
I've been against taking a WR early in this draft but that was assuming it was us taking a guy like Coleman or Fuller at 34. If Treadwell is magically there at 34, you'd probably be foolish to pass him up.
