Trying to predict who is worth what and what is a reach or a good value was basically thrown out the door in last years draft. I won't even touch on how teams supposedly reached for QB's because I was also in the camp that thought the Bears wouldn't take a QB at #3. The WR's were also over drafted according to the pundits. Fact is, teams will reach when they are desperate for a position of need.
Davis went 5, DJ had16, Mayock had 21, Casserly had 13
Williams went 7, DJ had 5, Mayock had 14, Casserly had 5
Ross went 9, Mayock had 12, Casserly had 14
