Three weeks into his first NBA season, Charlotte Bobcats rookie Kemba Walker isn't anything like dominant. The word is inconsistent, and that might understate the early on/off nature of the way he's played. Monday night at 7:30 the Bobcats play the Knicks at Madison Square Garden, where last season Walker conquered the Big East tournament as a prelude to winning the national championship with Connecticut. These days, Walker impacts an NBA game one out of every three tries.
