This is "Strength vs Weakness" both ways...
If ND goes with Coan, I think Ridder's mobility is the difference in an extremely close game.
If ND goes with Pyne, I think ND wins an extremely close game, IF Pyne can push the ball down field far enough to keep UC honest, even if he's not hitting a bunch of deep shots.
Neither team is going to run the ball well (on paper), and both defensive fronts have a huge advantage in pass rush (on paper).
UC's difference makers at WR are at their best getting into space, but Ridder needs time for those routes to develop. He can scramble around to buy that time, but I think Freeman will be ready for that, too.
I expect a game with both teams in the low 20's, tilting either way.
Coan vs Ridder: UC 24, ND 21
Pyne vs Ridder: ND 27, UC 24
