Quinn did 3 offense, 2 defense in Round 1
Mayhew 6 offense (Stafford, Best (trade up), Pettigrew, Ebron, Reiff, Laken) and 3 defense (Suh, Fairley, Ziggy)
Neither of them took a WR. Mayhew had Calvin though and added Tate. Quinn did Marvin FA and Golladay plus Amendola FA last 3 seasons. And of course Hock who is good
It's not number of 1st round picks. It's hitting on picks on day 1, 2, and 3 bringing in smart FAs at the right price, making good trades and then it is still up to coaches to make it work.
Trufant, Vaitai, Shelton, Nick Williams all can be good players. It didn't work out for various reason. Injury being a big one for the first 2. Nobody knew Trufants hamstrings would just blow up. And Vaitai would get a bad foot injury in camp
