That's also the last position group you want to start a true freshman at. Yeah Neal would play immediately, but that can't be said for the vast majority of true freshmen on the OL unless there's a huge need.
Freshmen will definitely get some PT just because of the new RS rules. But point taken that we won't really be relying on anyone as a true freshman. Payton will probably make the biggest splash given the talent and the fact the WR room is thinning out a little.
