It's called BPA my friend. Also ILB was a very underrated need as well. Arthur Brown was still a potential liability heading into the season as a starter and Mosley is the definition of a plug and play, day 1 starter, just look at his pedigree as a 2 year captain under Nick Saban at Alabama. Also look at how the board stacks at the positions you mentioned. Mosley was the only true stand out, 3 down ILB in the entire draft. WR specifically is still stacked heading into the 2nd and 3rd round.. we can still get Jordan Matthews, Moncrief, Latimer, Jarvis Landry, Davante Adams.. plenty of picks yet to be made before we start criticizing positions of need. One or more of these wr's in the mid rounds will be a stud like Keenan Allen was last year and that's why position plays a big part in draft value.
