LAS VEGAS - In Sundays loss, the Wizards offense looked best in the second quarter and in the final minutes with Earl Calloway running the offense. Yes, I can hear folks back in D.C. asking right now, who is Earl Calloway? Well, he's not an NBA player, but the 28-year-old starred in college at Indiana, most recently played with Wizards rookie Tomas Satoransky in the hgigh-end Spanish League and is a member of the Bulgarian National Team (more on this later)Callowayis also right now a symbol of perhaps the Wizards most intriguing roster decision in which the word amnesty is not involved.The debate surely going on inside the organizationis whether the team needs an experienced floor leader option behind John Wall and to steer a second unit that likely counts the summer league kids among its own.Receiving his first extended minutes with the starters, Calloway splashed down consecutive 3-pointers in the quarter. More impressive, the Spanish Leaguer crisply passed the ball and his veteran expertise led to sustained production. Oddly, Calloway did not register an assist in 24 minutes. Chalk that up to others misses. "Earl deserves to play, he makes shots, Cassell said. Also, we want to see if he can run the ball club. We're looking for somebody who can run a ball club. You know, we got John Wall, but after John Wall, we gotta figure it out, and that's what we're trying to do."Shelvin Macks ongoing transition into a lead guard turned ugly early against the pressuring D-Leaguers with three turnovers within the games first two minutes. He also shined late, making 4 of 5 shots in the fourth, and again played his best lined up on the wings."Its like taking a fastball pitcher and try and make him throw a knuckleball. He can get it, but its going to be difficult, Cassell said of Macks development. Hes getting lots of on-the-job experience. Hell be fine.Whether fine is good enough - and happens soon enough - entering a season where the teams owner said another lottery trip is unacceptable is the issue. Considering the Wizards current top four guards have a combined five years of NBA experience, finding another steady option that can run the offense remains a consideration worth exploring.
