Darrius Heyward-Bey. An example of a WR who, although terrible at his "primary" position, and definitely overdrafted by his original team, was able to become a contributing member of the Steelers. Now, his contributions were largely limited to STs, but, he provided more in Pittsburgh as a player than he ever did in Oakland. You don't know what you could get until you bring them in to camp. And, as someone posted earlier, nobody is asking or expecting Boykin to come in and be WR1 or WR2, but if he can provide more than James Washington did, it's a win. If he can't, you cut him before the season and gain $2.5M back in cap space.
