IMO You can't just assign a number of victories, or a certain placement in the Eastern Conference to the value of any one player. There are always extenuating circumstances.
The Celtics brain trust will look at the team through film, with honest and open eyes. They'll make a decision as to why the team lost a series.
If its found that the Celtics are loosing playoff games because the team defense is weak with IT in the lineup, and that fact overrides his offensive output. Then he may not get his Brinks Truck.
It's about winning a ring, not collecting jerseys. As the Celtics accumulate more and better all-around players, the value of IT will reduce because of his being a liability on D.
This year, with the addition of Hayward, and Tatum, and the growth of Brown, and even the presents of Morris... expect his shot attempts to go down.
