The Boston Celtics have a somewhat unpredictable roster when it comes to the big teams in the East, but things are shaping up for the Brad Stevens-led team. They also have an exciting young rookie in Tacko Fall.

The big man is participating in Celtics training camp, trying to make a space for himself. What he has shown so far proves that he might become the 15th man for Boston.

Fall first showcased his skills after imposing his will against Enes Kanter down low, dunking all over his teammate:

Fall was also seen shooting corner 3-pointers at practice. He showcased good shooting mechanics for a guy of his size, which could become a useful asset for Boston moving forward:

While his position with the team is far from secure, Fall is already building quite a reputation among Boston hoops fans. He's the tallest player in the NBA, and he has shown that he has skills to back up his physical gifts.

The 23-year-old was a consistent presence for UCF during his four years for the team. He developed into a great inside presence at UCF, averaging 11.1 points, 7.6 rebounds, and 2.6 blocks in his senior season as a Knight.

Tacko Fall's agent is doing everything he can to make him a permanent fixture on the team this season. If things go well this training camp, he could very well get that 15th spot.
