I like the latter especially if that center is Roy Hibbert. He is a player that doesn't need a good point guard to be successful. So drafting a rookie point guard like Marshall won't affect Hibbert's production negatively and might help since Marshall is a pure point guard. Now if you like the former like signing a Goran Dragic and drafting a center in Andre Drummond then there might be question marks. We don't really know how good Drummond is but he has a lot of potential. I'm okay with Dragic, as long as he isn't overpaid.
