It is very possible that this is KLS's second visit to Storrs.
A few years ago, Bonnie made unofficial visits to Duke, Maryland and UConn (possibly others). It is likely that she was traveling by car and, if so, it may have been a family trip with at least one parent plus Karlie and Katie Lou. I confess to be speculating about a reasonable set of circumstances.
Bonnie obviously selected Stanford and her role has been clearly defined as an off-the-bench long-range shooter. And she is good at that.
There were indications that Karlie was really impressed with UConn, to the extent that some believe it would have been her first choice. But it is a matter of record that the close Samuelson family was dealing with the loss of a loved one (her uncle -- dad's brother) and Karlie's selection of Stanford may have been to some degree influenced by her desire to stay close to home under these circumstances.
That situation apparently has faded from focus and KLS is not only clearly free to choose what's best for her, but enjoying full family support in this very important matter. Geno will exercise his powers of persuasion (assisted, I'm sure, by KML) and at some point Katie Lou will make her decision and announce it.
I understand that she has Olympics ambitions. If that is true, I like out chances.
