I like Terrence and I think he'll be a valuable contributor.
That being said, it's obviously absurd to say he's already better at getting to the bucket and converting than Napier or Boatright. Samuel got minutes in the tournament because other teams were loading up on those other guys. He has not yet been asked to run an offense for 40 - or even 10 - minutes, and he certainly wasn't the focus of any team's scouting report like those other guys. I'm optimistic about him but I think some people are going a bit overboard based on what he showed in the tournament. (But I don't think his jumper was "beyond ugly," I don't think anyone would confuse him with a natural jump shooter, but it looks like he's got something there to work with.)
