This article from Purdue's SBNation site says he's a combo guard. I'm pretty sure he's capable of playing at least spot minutes at point guard.

If Isaiah Washington is our point guard of the future, I sort of wonder if we'd be a very attractive destination for a pure point guard in the class right behind him. I'd guess Washington and McBrayer are getting most of the point minutes in 2018-19, and maybe Coffey and Harris will get some too. I'd worry a little bit about a 6'0" or 6'2" PG getting stuck behind Washington for most of his college career. Eric Hunter is listed at 6'3" and can play off the ball, so he can play alongside Washington. Brendan Adams is a 6'4" point guard, so maybe he could play off the ball too.
But then we took Kevin Dorsey and Jarvis Johnson in the same class a couple years ago, so maybe they will take another point guard. But Eric Hunter seems like a pretty appealing option.
