That's exactly what TG is good for, against average QBs. He makes good QBs looks like elite QBs, and make average to below-average QBs look like bad QBs. Since there are much fewer good QBs than average to below-average QBs, his overall stats are pretty good. If your goal is to win about 9 games a year, he's your perfect DC. If you want to win a title in SEC, you need to look elsewhere.
