This is a DT heavy draft. Many teams, not just Marinelli, love to throw waves at offenses. Crawford and Irving are building blocks, but competition is the way to bring out the very best in anyone. And let's not forget injuries or off field issues, you just never know.
IMO, draft heavy at these positions now while the supply is at its peak. Trade down (multiple times if possible) and pick up Billings and Nkemdiche (could drop to 2nd like Gregory) with early picks. Then draft at these positions again on the final day, looking for projects that can be stashed and developed on PS. We may get lucky and one will supplant starters or early picks (creating trade opportunities).
I really like the following guys in the 4th-6th:
3Tech Javon Hargrave, 6-1 295, South Carolina State - 16 sacks, 24 TFL in 2014; 13.5 sacks, 20 TFL in 2015; 2x MEAC DMVP
1Tech OJ Mau, 6-2 310, Gardner-Webb - 4 sacks, 10 TFL, 55 total tackles in 2013; 3 sacks, 10 TFL, 3 FF, 1 FR, 60 total tackles in 2014; 2x Buck Buchanon Finalist
Undrafted FA's
1Tech/3Tech David Onyemata, 6-3 300, Manitoba
1Tech/3Tech Greg Milhouse, 6-2 300, Campbell
