Pocket presence, precision, reading a defense, standing tall in the pocket, could take a hit, essentially everything you want a pro-style QB to be. This was obviously before his shoulder got wrecked in 2015 and Ricky Rahne ruined his mechanics trying to turn him into a college spread passer. Had he transferred either after 2013 (which he should have and it would have been easy due to the NCAA's vile and 100% specious sanctions), 2014 (he really should have but the before mentioned persecution by the NCAA had expired) or 2015 (very easy as a grad transfer), he would have had no shortage of suitors. A very vocal subset of ill-informed Penn State fans love to bash him but had he transferred he would have been highly sought after by every pro-style team in the country including Stanford, Michigan, Michigan State, Alabama, Georgia, USC, Wisconsin and Iowa, all of whom went through some type of QB transition during the timeframe.
