GP's MO has never been overconfidence more like over fear or over cautious. He doesn't like giving out injury reports, closes practice from reporters, we didn't even have an open spring game this year which he even downplays every year by calling it a scrimmage. He usually gets wrapped up with all the coachisms about winning by 1 more point, playing em one at a time, etc. He was also very complimentary of ISU's defensive line and offensive line's size and discussed the fear of them doing a number of trick plays (fake punts, onside kicks, etc.).
TCU also lost its 20th player this year with the mentioning of Austin Terry leaving the team for medical disqualification. So the one thing I don't think it would be is confidence. They play up to this point would not support that type of thought. Instead, it has been a long and crazy offseason and football season already. And TCU hasn't even got into the heart of the Big12 schedule yet.
My guess is you were seeing him come up for air so to speak rather than pass any judgment on any opponent. He has already given the we have to take X opponent very seriously already 4 times. I highly doubt he thinks Iowa State is a worse opponent than Virginia, Grambling and Kansas.
The other thing that he might have been happy about is the release of the information about TCU setting up to play Ohio State in a home and home series. Frankly, he is probably just happy to be out of the rain from the SMU game and in some dry clothes.
