Tried to search for it but came up empty.

What happens if you fail on 2 promises? Or just 1? Do you loose a letter grade in something? Do they just transfer? Just thought I would weight my options going into this non-conference schedule.

Is it a bigger hit with 2 promises not full-filled compared to 1? What about on 2 players missing 1 promise each?

You're rep takes a hit and they transfer. Depending on the player though there is usually a bit of leeway. It used to be if you keep it within 80% of your promise you were ok but I think they've tightened it up a little bit. It just depends on the player now I believe.
