Martini/Coney and Tranquill/Bilal platoons at the outside with Morgan in the middle and ND is in great shape there.
D-line is interesting. I actually feel pretty good about 3 of the 4 spots after spring. I think the Hayeses will be good on the outside and a Cage/Tillery platoon can be really good at nose. The problem is the other DT spot. Bonner would be great as a change of pace guy there, playing 25-40% of the snaps, but right now he's the starter and there is no legit back up.
I share your concerns at safety.
I would probably put corners ahead of WRs right now. I think with Love, Watkins, Vaughn, Pride and Crawford ND is in great shape at CB. WR is still an unknown outside of St. Brown. WR could end up being really good or guys like Claypool and Stepherson might be a year away (if Stepherson is around at all).
