Has Geno EVER lost a freshman or sophomore to transfer because she didn't like his decisions about playing time?
I certainly acknowledge that there are players who transferred because they recognized that they would never get the playing time that they hoped for (because other UConn players were better): Courtney Ekmark, Lauren Engeln, and Michala Johnson for example. But those players all transferred after their sophomore year, after they gave it everything they had and were forced to acknowledge that other players on the team were better (or at least the coaching staff considered them better) and would continue to get more playing time than they would.
But if there has ever been a freshman or sophomore who transferred because Geno didn't give her enough minutes because she didn't meet his expectations in practice or in the few game minutes that she got, I am not aware of it. From what little information we have, neither Sadie Edwards nor AEH fit into that category.
And there have certainly been those who got the "pine treatment" as freshmen, and who later got their act together to make major contributions: Gabby Williams and Mel Thomas, for example.
I assume the OP has seen Geno's comments on this specific subject: "If they learn as freshmen that they will get minutes even if they ignore instructions, then there is no coaching them when they get to be juniors and seniors." Quite a bit of truth in that, I suspect.
