The A10 getting 3 bids actually hurt Dayton. They were in the Top 35 in Pomeroy, and they had a better RPI than Minnesota or Florida (both at large bids).
If Dayton didn't lose those two final reg season games, they'd have been a bit closer to getting a bid.
Sounds like losing the last 2 games actually hurt Dayton. Not the number of bids.
