During pickup games at the Boston Celtics practice facility, Marcus Smart has found himself matched up at times against Rajon Rondo. "It's totally different than what I expected it to be," said Smart, who was among the Celtics players attending the Shamrock Foundation's fundraiser. "He's one of the premier guards and he shows it and his play shows why he is. Some of the things he does on the court, it's like, 'How did he do that?' Just being able to be around him and learn from him is an amazing feeling." After the Celtics drafted him, talk immediately shifted towards Smart as the heir apparent for Rondo in Boston. It's a logical line of thought, considering Rondo will be a free agent next summer and Boston used the No. 6 overall pick in last June's NBA draft to select Smart, a 6-foot-4 point guard from Oklahoma State. Aware of this, Smart was prepared to deal with a not-so-friendly Rondo heading into camp. "I was expecting him to . . . kind of shun me off and push me to the side and kind of learn on my own," Smart said.
