See, this is what I love about our team. There is no one answer to this question. You could conceivably argue that any one of a dozen players is the MVP of the team. You could look at Avery, the longest tenured Celtic for bringing leadership to the team. You could look at Thomas as being the spark-plug that brought the team together. You could look at Turner, who has excelled in every role Stevens has put him in. You could look at Bass, as a steadying force, on the court and off. You could look at Smart for sparking a defensive intensity. You could look at Zeller, the surprise of the year, and a surprising contributor in our frontcourt.
Finally, you could look at Stevens as the architect of this messy, imbalanced roster that has somehow bonded together and fit just well enough to make a playoff push with 5 games to go. This is the most likable team we've had since 2012 at least.
