First round picks are cheap. I agree, you don't need a true #1 to win and paying $20+ per year is cap suicide (unless you have a legit rookie QB), but that's why you take one in the first round. They are cheap... and in a time when WRs are getting drastically overpaid, an added bonus is the 5th year option. That would have avoided the entire AJ Brown fiasco (at least for one more year).
I'm not super sold on Burks as the player, but it doesn't matter if you're a run first team. Drafting a WR in the first is smart. Now let's see if it work out with Burks.
