I don't think Mauck was off - I think he was Mauck being Mauck. His stats show that he hasn't had an acceptable completion % for the last two years and I doubt that will ever change. Dog likes stats and has said that stats tell the story. Well here are MM's stats:
Cmp Att Pct Yds Y/A AY/A TD Int Rate
*2013 68 133 51.1 1071 8.1 9.0 11 2 143.1
2014 209 395 52.9 2551 6.5 6.4 23 11 120.8

Take in to consideration that some of those stats are padded with the Murray States and Arkansas States on their schedule. He has averaged 52.5% completion rate in over 500 attempts. I don't think that is an acceptable rate for a supposed premium level QB in NCAA Div. 1. You can make all kinds of excuses (poor O-Line, receiver drops, O-coordinator sucks, etc.) but really good QB's will have better numbers. I think he regressed in his second year. I hope that trend doesn't continue!
