Celtics player power rankings: Robert Williams is on the rise

With two months of the NBA season in the books, there’s been some significant movement within the Celtics player power rankings as the C's have found their rhythm with eight wins over the last nine games. A look at how each roster player stands after an 18-11 start to the year.

14. Guerschon Yabusele (Previously: 13): Some incredibly bad luck for the second-year forward lands him in the bottom spot of this list. He played some of the best basketball of his NBA career a week back in Chicago before suffering an ugly ankle sprain that will sideline him for at least another few weeks. With other injuries piling up in the frontcourt during early December, this is the one chance that Yabusele could have had to earn some regular rotation minutes. Instead, he will have to work hard over the next few weeks to get back into basketball shape once he’s cleared to return to the floor. Look for a couple stints for him with the Maine Red Claws before we see him back with the big club.

13. Brad Wanamaker (14): The 28-year-old rookie's long wait for an opportunity at the NBA level finally paid off in the past week as he saw meaningful rotation minutes off the bench in wins against the Pelicans and Wizards. The 6-foot-5 guard acquitted himself better in those matchups than he had in the preseason, showing off a nice mix of 3-point shooting and finishing ability when opponents closed out on him. He also dished out four assists in just 18 minutes last week, giving Brad Stevens some added confidence that he can turn to him in a pinch. For a guy who might be viewed as expendable when the trade deadline approaches, he helped to boost his stock in the last month to stick around.

12. Semi Ojeleye (10): Like Wanamaker, Ojeleye had been pressed into a larger role by injuries but he failed to take advantage of his opportunities, particularly on the offensive end. The second-year forward continues to show far more aggression this season (11.1 attempts per 36 minutes is almost double his average from last year) but it’s not producing any added efficiency for the C’s from downtown. He’s shooting just 28 percent from beyond the arc and is a paltry 2-of-14 from 3-point range over the last four games, including an ugly 1-of-6 outing in Washington last week. Like some of his younger teammates, Ojeleye would probably be better served to show some more discretion with his outside shot.
