Insiders are beginning to report that Shea will put his name in for the draft but is nearly 100% planning to return next year. That's huge and makes sense all around. He'd probably be ~8th taken at his position, which would make him a 2019 midrounder, and I'd say he could parlay a return into a 1st/2nd Rd selection if he stays and he doesn't dip below his current level of play.
And then there's the offense, which will return almost everyone - only losing one OL (JBB), Higdon and Perry. So: Patterson, in his final year of eligibility, throwing to Collins/Black/DPJ and Gentry, behind an ascending OL? Yes please!
