I'm late to this debate... But I'll add this.
The question was who is the best player, not who won the most titles etc..
I'm going with Maya, Geno has always said there is only one player who came into his program ready from day one and that is a fact! Also, there is a reason why she is the all-time scoring leader in the program and that is called consistency... And she did that on both ends of the floor, never lacking for energy or effort.
Stewie and Diana are tied for 2nd place.....
And though this is about what was done at UCONN, when you look at the impact she also had at the next level it's very difficult not to give her the edge as the all-time great, so far.
If I'm picking a player to be my franchise player I'm Picking Maya first and Stewie second. But that is just me..
