It's certainly a bonus to have highly athletic, highly skilled players with experience against the best competition. However, those players are a tough acquisition for non-P5 programs like Mason.
With a coach like Paulsen, you find players with two out of those three attributes, add intellect to the equation, and coach up the remainder. It makes sense to grab players who are athletic and skilled and then build up competitive prowess. Look what Coach P did with Marquise and is currently doing with Otis and Relvao. All three players took their athleticism and skills to build greater competitiveness and confidence as last season progressed. Their improvements were starkly clear.
Therefore, I'm not worried about the level of competition that Paulsen's recruits have faced in HS. If a player can shoot, move quickly, jump high, and see the court well, then mold that player to be the competitor that you want.
