Schwartz is a tackle. A very good tackle, if FO is to be believed. He proved it last year.
If Otah for whatever reason does something this year that makes it clear he can't play tackle anymore, or has a career ending injury, your solution would be to draft another tackle? Ignore all the positions of need and fortify a position of strength?
Yeah I don't have their draft board in front of me but I'm also not a slobbering cretin.
it remains to be seen if Schwartz will actually pan out, he had his shaky moments during some games. I know those were probably mostly at guard. But I wouldn't object to drafting a RT especially if it was BPA.
