THIS! 1000%. We can get away with it against Mercer. You're 100% right. When TJ keys in on receivers that's when his INTs come. He has to learn to either throw it away or run and get a few yards.
Overall, I liked how TJ and Robbie were used. Who knows if Robbie will get half the snaps against the better teams (I hope so) but it's clear to see why he deserves those snaps. At times, it felt like a flashback to NM. TJ looked better. He just needs to limit the INTs and that could help us tremendously.
