Just my opinion, but I don't think we're near as needy as we were last year with Rivers, who couldn't run goal line or sneaks.
I like Wentz's size profile better than SE's for that type of stuff. His AVG rushing his senior year was better than SE's (3.3 vs 4.7).
Not saying SE couldn't be effective doing so, but so is Wentz. I wouldn't carry a guy on the 53 for just that. If you're just concerned with injury to Wentz, then just go wildcat with Taylor. Or heck, Deon Jackson, if he makes the roster, can also throw lol.
It's a bit easier grading OL IMO. You can measure success rate, or simply yards over each gap. You can measure pressures coming from each gap. Not saying play calling is irrelevant, but it's not a huge bearing on what they are measuring. Over the course of 16 games, things even out for most players.
