I think that if an ot arrives, with experience in another position: ekwonu, petit frere, green it is likely a first, if they are a single trick they will wait for lower rounds, a 4 round better than Villanueva should not be difficult to find, Let's look at Georgia, Arkansas, Nebraska, Wisconsin, Iowa, there's a Wagner out there for sure.
safeties there are not much interesting, many hitters, few hawks, linebackers just the same.
defensive linemen and edge there is enough.
Jordan Davis is the renowned one with 6'6 340 but Ridgeway is 6'6 325 and has twice the engine and mobility, the more I watch the videos the more I like the Ravens
