Definitely taking 3-4 DTs.
I just can't see 4 DTs -- three maybe. It's been said we're taking 4 LBs (which I don't believe either). We also want to take 2 RBs and 2 TEs. And we're likely taking 4 WRs and at least 5 DBs. The numbers just don't add up.
I'll assume we can take 25 schollies for the '20 class, I'd guess
4 OL
1 QB
2 RB
2 TE
4 WR
5 DL (2 DT, 2 DE, 1 that can play both)
3 LB
5 DB
That's 26 right there. And looking at our depth chart, we need DEs more than DTs.
