Nobody got hurt and, uh, that's kind of it.
Naturally the spring game is the kind of thing that you should never read into deeply. If it was, Nick Scott could win the 2015 Heisman Trophy (which he may do, and it would be awesome, but I will bet $5 that doesn't happen).
Really, the 2015 Penn State spring game didn't tell us all that much regarding the 2015 Nittany Lions. Team Blue took down Team White, 17-7, in a perfectly cromulent football game.
There's no reason to get up in arms about the sacks Christian Hackenberg, uh, "suffered" at the hands of the defense of the white team.
