Men and women choose schools for different reasons, and their goals tend to be different. But, we might learn from what we have seen in women's softball.
1. There is no wholesale movement of players to or from successful programs.
2. Few impact players transfer.
3. Usually, a transfer involves something other than just wanting to play for a winning team.
Recent transfers to and from OU: (off the top of my head)
Shelby Pendley: from Arizona to OU after her freshman year. Two programs rated about equal at the time. She just wasn't happy at Arizona.
Tony Nirschi: from Pitt. Had been fairly successful at Pitt. Didn't play much at OU. No reason given for transfer. No real gain in playing time.
Kelsey Stevens: from Stanford. Several pitchers have transferred from Stanford recently, resulting in a decline in their program to maybe the worst in the Pac 12. Recent coaching change resulted. Stevens came to a program in which Gascoigne and Ricketts had graduated, and she led OU to the CWS as our only legitimate starter. Ineffective as a senior. Apparently, some problems at Stanford. Hoover of LSU also transferred from Stanford.
Paige Lowary: from Missouri. This wasn't so much a transfer as it was a resurrection. After a decent freshman year, Paige was hit in the head with a line drive. She was out for a while, appeared to be afraid to be on the mound. She lost all interest in softball and was strongly considering just quitting the sport. She transferred to OU and was a star late in the year. OU solved her emotional problems by giving her confidence.
Dalton: From OU to ? Forget where. She missed half of her freshman year with various emotional issues. Didn't like to work out. Class attendance problem. Just needed to grow up. Couldn't seem to do it here. Apparently, had similar issues in highschool.
Destinie Lookout: from OU. Wasn't likely to play much. I don't know if she is still playing.
Jadyn Chestnut: After FR year, transferred to Central in Edmond where she has been very successful. Wasn't likely to be a key player at OU. Not quite high D-1 talent.
Brit Finney: Transferred to Mississippi. DP most of the year. Pitched a one-hitter (?) against Bama late in the year. Coming around. Control problems at OU, Possible parental influence. Unhappy.
You see this much activity in a lot of sports. Players who don't see playing time may leave, even if they have to sit out a year. None of these were likely to be influenced by having to sit out a year. Other factors intervened.
Mostly, what we see is players leave programs for a reason. If you see one transfer, you may see several. It is often due to something wrong with the program. Missouri has had a lot of transfers. I haven't seen many transfers to other major programs, and almost none of consequence. In some way, some transfers are somewhat like a male going pro early, just to get away.
