Rondo is the best player on the Celtics, but there's a catch.
By far the most polarizing player on the Celtics, Rondo delights and frustrates pretty much in equal measure. One minute, he's barely showing up for a brutal loss in Toronto, seemingly out of anger at being left off the All-Star team (which he would go on to make anyway, as an injury replacement), the next he's exploding in one of the best individual performances in the entire league all year—a 32-15-10 masterpiece in a win over the Eastern Conference's best teams, the Bulls.
And then, with injuries riddling the team's already shaky depth, he gets angry at a non-call, fires the ball at an official and gets suspended for two games.
It's hard to know what the Celtics are going to get out of Rondo from one game to the next, and that's a risky situation if the plan is to let Garnett, Pierce and Allen go either after this year or during it and subsequently hand the team over to the mercurial point guard.
Rondo, for all of his incredible ability on both ends of the floor and on the glass (he's one of the best rebounding guards in the league), is still something of a liability down the stretch of games. He's shooting 48.5 percent from the floor but still misses far too many mid-range jumpers—a shot opponents dare him to take more often than not.
And he still can't shoot free throws (61.5 percent this season, 62 percent for his career), which inclines whoever is guarding him late in games to back off even further given his reluctance to take the ball to the basket (one of his greatest strengths) for fear of getting fouled.
When Rondo is going good and not acting like a petulant teenager, he's the best player on the team. But as he continues to improve, his main targets continue to slow down, making it harder for him to play his game. Rondo's missed eight games this season due to injury and two more thanks to that suspension. The Celtics have to be wondering how many more times this year, and beyond, they'll have to worry about him not being there.
