I've actually grown quite fond of having someone like DD (maybe with slightly more bulk or physical toughness, like Roscoe) at the 4, rather than another paint-oriented big body. It does wonders for our floor spacing, opens up penetration and cutting lanes, and forces the defense to respect the 3 point shot (or punishes them if they don't).
As far as recruiting goes, I think that's the archetype we need to try to go after for 2015, to replace Daniels. We could also use another big to complement Brimah/Nolan and Lubin/Facey, but I think it's most important to keep someone at that stretch-4 position, which has caused major matchup problems for the opponent and fairly few matchup problems for us.
I also think we're pretty much all set at the guard position for 2015, unless there's an absolute stud we want to bring in. In 2015, we'll have Purvis, Samuel, Cassell, Jackson, and Ali to split time at the 1/2.
