Excuse my confusion here. JA is listed as a SG (as was Prince Ali, so I can understand if Prince de-commited bc he heard about JA) and Will is listed as a PG. Why would JA's commitment effect Will's commitment?
Although JA might be listed as a SG, from all that I've read is really more a Combo Guard. Now CGs can be defined in various ways, but he's likely cut from the same mold as Kemba, Bazz and Boatright, who were all lead guards in HS who would have the ball in their hands to create or deliver to teammates. I tend to like those types of guards as long as they have shown solid instincts to deliver the ball to open teammates who are in good scoring position, but can also create their own offense, taking their man off the dribble and score from 3, midrange and at the rim. In the case with Kemba & Bazz, they were/are more shoot first combos with solid passing skills who can play off the ball, compared to some combos who are more pass first guards (some who are exceptional at delivering the ball to the right teammate) but are capable scorers when needed. The former is the Kemba type combo the ladder is the Steve Nash type lead guard.
There is a 3rd type combo, such as a Ben Gordon, who has PG size, was put at the 1 at times at UConn, but simply lacked the ability to see the floor as far as delivering the ball and running an offense. You can get away with spelling your starting PG for a few minutes with this type of guard, but they are not ideal if your team doesn't have a good lead guard who can stay on the floor for most of the game. From what I've heard about JA, is he's more cut from the Kemba & Bazz type of mold. On a side note, based on what we saw late last season from Boatright, he began his transition to lead guard and I have full confidence that those skills will only get better as the 2014/15 season goes on.
UConn's lead guard situation, both present and future, looks quite bright.
