I want everyone to take a deep breath and really think about this.
I am, like a lot people, an "at will" employee. I can leave whenever I want for a new job. However, I haven't. Why? Because I like my job. Generally speaking I like my coworkers and I know the quality of work I can expect from them and they the same from me. I know where I stand with the power structure of my firm and I'm happy with my work-life balance.
Stability. People, whether they know it or not, crave stability.
Players are not just going to transfer for the hell of it.
These players in their times at their respective schools have developed a routine. They've made friends, girlfriends etc. They have a developed a social network.
Furthermore, they know their teammates and they know the coaching staff. They know the expectations of the staff, the rules, the plays, what to expect at practice, what is expected of them in the classroom etc etc.
Will a rule change such as this cause increase in transfers? Yes, definitely. Will it become the Wild West where entire rosters switch over every single year (more so than what one and dones do already)? No. Because players are human.
Will this rule change, if it happened to today, negatively affect UConn? Probably. Especially in the short term. I can't really say I blame players for not wanting to play for this coaching staff in this league (not to turn into yet another thread on either of those subjects).
This rule will have an impact, maybe a significant one, but not on a scale that will bring ruin to the sport. If this rule goes into affect, it could seem staggering at first but we will recalibrate how we follow transfers, recruiting etc.
