One of the newest trends in the NBA has been to play two point guards at the same time. The idea has been to increase the team's pace, passing and fast break opportunities, without hurting the team defensively. Teams that have executed this two PG lineup successfully (LAC, DEN, MIN, others) while arguably sacrificing some defensive size against the other teams shooting guard.
With the Washington Wizards being one of the worst passing teams in basketball and a team that is openly trying to play faster, shouldn't Wittman give the Wall-Mack backcourt combo a little run? I think Wall is big enough and athletic enough to guard most twos (at the very least in short stretches). Mack and Wall are possibly the two best passers on the team, and Mack's shooting is not too much of a fall-off from Young/Crawford.
I'm not saying this should be a starting lineup, but a couple 3-5 stretches each game would be a nice experiment to see. Currently, I believe Wall-Mack combo has gotten less than 10 minutes of run, if any. (I presume because it's not on this list, http://www.82games.com/1112/1112WAS2.HTM ).
I'd like to see Wittman at least experiment with this. I think it could help take some pressure off of Wall and eliminate some of the turnovers. And hopefully, get more offensive player and ball movement.
