None of our incoming personnel are going to make a lick of difference if Hewitt doesn't seriously alter his approach to preparation, in game adjustments and most importantly defensive scheme.
He's got a very bizarre roster configuration next year and he's going to have to figure out a way to cobble together an offensive scheme that includes a lot of tweeners. I don't see any way a 4 out, 1 in offense can work with so few shooters available. We're either going to have rely on our length and athleticism to press and run (which means devising a much better press than we currently use) to mask what will be our half-court deficiencies, or we're going to have to find a way to become an inside-out team, posting up two players and freeing up what 3 point shooters we do have (Holloway, Marko*, Royal*, and Gray). In either case, he's going to have to change what we were doing last year.
As for defense, we might be able to mix in man-to-man if (and this is a huge if) Lockett and Mayimba are as good on defense as they have been advertised to be and can come in right away and guard A10 guards. Otherwise, we should run a lot of zone, and he should probably add a 1-2-2 with our base 2-3.
*are for players who have the potential to be 3-point threats but haven't shown they can be yet.
