At the time, I didn't think Storr was a good value. His price seemed to much based on hype/potential rather than actual performance (low efficiency even adjusted for usage).
It's possible that, in hindsight, he will end up being a good value (either from improvement or NIL inflation), but I can't fault the staff (or donors) for dropping out of that bidding war based on presumed market prices at that time.
I think there are other targets since then that I'm more disappointed we missed, but I don't know how real of a chance we had with any of them. And we still don't know who we will get.
