Don't know on LaFond, but I'd imagine, based on what I've seen, if he goes in the top 15 rounds, he's gone.
I think Scheiner will get drafted in the top 20 rounds and is probably gone. He's always been someone that's been downgraded because he doesn't have the physical tools that scouts love, but he's produced at every level. He doesn't have anything to prove in college anymore and coming back won't help him in the draft next year.
I was surprised to not see Cumbie there. A lefty with his abilities should have teams salivating. Then again, he probably would benefit from another year as the Friday night guy for an entire season and pro teams may see it that way too. Out of the three, he's probably the most likely to be in a UH jersey next year.
