This thread has received so much input I figure "what the heck, I'll throw my uninformed two cents in."
At one time both UConn and Tennessee backed off of Massengale. Then Tennessee jumped back in. Using that little nugget I'll extrapolate wildly, because that's what us fans do
. I think towards the end of Summitt's career she was pursuing talent and athleticism without much of a plan behind it. Maybe that's the way she always recruited, but she was once able to mold them the way she wanted. Whether or not that was once true, it was not towards the end of her career. Thus Tennessee was "stuck" with highly ranked talent and athleticism but were missing some of the ingredients mentioned in ciarlante's excellent post. Injuries compounded the problem, but the problem that latione referred to exists aside from the injuries.
Some people fault Auriemma for going after too few recruits, but there is no doubt he is much more deliberate about it than Tennessee has been in recent years. We'll see if Warlick turns that around.
