Not every player fits every system or coaching scheme. To me, EGs personality, body, and skills weren't the perfect fit for ND (pressure, leadership requirements, etc), and BK's system.
Compared to his time at ND, his attempts and completions are down, but % took a nice jump (sitting at 67%), YPA about the same, sacks are less than half over 2014, and zero INTs and fumbles. RAT is up to 151.
Anyway you look at it, he's being asked to do less and looking better doing it.
Will he rise to the occasion when challenged later this year against better opponents (Louisville, GT, Clemson, Florida, and Bowl.... Only time will tell. So far I think it's been a good move for both him and ND.
