I agree with what you're saying but I just want to add in my 2 cents.
(1) If they happen to RS, that does not mean that they aren't as good as we hope they'll be. Playing OL in the Big 10 is a "man's game" and there are a ton of great college/NFL lineman that weren't entirely ready to make that step at 18/19.
(2) As high as my expectations are for both of these players, I kind of think of both of them as having unlimited potential but could use a year of refinement. PJ talked about wanting Dunlap to lose a little weight and Faalele is new to football. I know some times when people on Gopherhole talk about slight changes recruits need to make before being quality Big 10 football players it is seen as a slight (remember when people had the audacity to say that a 240 lbs OL was going to need to hit the weight room and get bigger?), but I don't mean this a a slight to either of these guys. I am incredibly stoked about these two being on the team and I was way more impressed with the All Star game footage of Faalele than I thought I'd be.
