When the Celtics lost Al Horford for nothing last offseason and traded Aron Baynes, Daniel Theis comfortably slid over to the center position and had a top 10-15 season of any center in the NBA last year. Now that Gordon Hayward left the Celtics and no wings remain, the Romeo Langford and Aaron Nesmith pressure increases.
Langford rarely played in his rookie season and is out into this next NBA season with an ankle injury. Nesmith enters as an unproven rookie. Them and Semi Ojeleye will be tasked with filling the bench minutes at the wing.
