It's hard to tell you exactly what to do, without knowing more info: how many AP did you use? How many HV, CV? How many cycles did this take (I ask since sometimes transfers come and go/sign very quickly)? If it only took 2-3 cycles, there is not much you can do to react. If you went all in (20 HV and 1 CV) and still lost, then it was just a factor of the prestige and the other coach also going all in (or close to it).
If it took many sessions, then you should have known there was not much you can do... with such a prestige disadvantage, it's a big uphill battle. It is always a bummer when the roll should have gone your way 67% of the time.... On the flip side, you may win some of those when you are on the 33%.
I had a guy last season sign with the school that had 12% chance... I had 32, someone else had 37, and a fourth guy had 19... but we all lost!
