After all, Fall was signed via Exhibit 10 contract by the Celtics, therefore it was even expected at first that this tall guy might not be included in the Boston Celtics' final lineup. His summer league game stats will now be evaluated.
But honestly, even for let's say he will get the last roster spot for the Celtics, there's another opportunity for him to showcase his skills and that is thru NBA pre-season games (if ever he made to get a spot). From there, even Celtics will limit his minutes on the floor once Season commences, other teams might now show interest in this guy after seeing him in good action at pre-season games despite after some evaluations did by them prior NBA draft pick that it's risky to pick this guy.
Fall should really work hard to make a buzz to the point that he should be a monster for every given playing time.
The way his contract works shows that Boston Celtics are not taking any risk with him and Tacko Fall being part of the team isn't guaranteed yet. If he doesn't showed any improvements this offseason then the best thing he would get is to be offered up a two-way contract and prove himself in the G-league which I think he will be a contributor right from the start. I still see him as a raw talented player but not so talented enough to be a contributor in the NBA's regular season. This is a win-win situation for Boston on snagging one of the most overlooked players in the NBA draft.
