I've fallen out of love with Porter/Smart recently, moreso Smart.
I'd take Oladipo and maybe even Burke over both; but certainly Oladipo over both.
He flashes a really nice handle; check out 3:25 and on from the draftexpress video.

Indiana Coach Tom Crean seems to be getting more comfortable using him as a creator, however, as almost 20% of his possessions have come in isolations or as the ball-handler in pick-and-roll sets. He is far more comfortable dribbling and finishing with his right hand at this stage and doesn't show much in the way of advanced ball-handling skills, but he's still able to get the basket at times, as he is very difficult to stop once he's built up a full head of steam and is able to utilize his blazing speed.
And look what he does at 2:27 in this video to MKG:

The guy has shown he can improve tremendously; his elite level athleticism, elite level defense and energy, vastly improved jumpshot, and flashes of an isolation game put me on board with Oladipo as a top three prospect; if he finishes developing his handle and he can become something of a shot-creator, he could be one of the best all around guards in the league.
