I don't think that a Scoot/Sheppard back court is what we'd be banking on, if we drafted Sheppard. I think we'd be hoping that Sharpe would be the 2, and that Scoot and/or Sheppard would turn out to be a perennial all-star type of guy. We currently have none of those on our roster, and as much as I like Scoot there's no guarantees there. If both of them turn out to be awesome, either they can start together or you move one for value elsewhere.
If there is a prospect on par with Sheppard but who's a bigger body, then I'd probably prefer that, but with Sheppard being such an anomaly in advanced stats and the lack of certainty with other prospects, he's currently a guy I'm most interested in if he's there at 7 in spite of the lack of fit.
