T Sam plays the way we need Purvis to play. Ollie's drive and kick offense needs the wings to make immediate reads. Shoot it, or put it down draw the defense and kick to the opposite wing or take it all the way to the basket. Watch T Sam in this role and how quickly he makes his reads and then watch Purvis do the same.
Yes RP has a better jump shot (and therefore upside) but until he starts to react instinctively (like Tsam does) then he's actually less of a viable option than TSam at this point. Thankfully, we're UConn, and we know that its not about winning games in November so Purvis is going to continue to get developmental minutes.
@HuskiesAllDay isn't wrong but I do think he/she are shorting T Sam a little too much, and I bet a good deal of the forum taking shots at AD remembers "This Team Stinks"
