Isaiah Thomas was without a doubt the Celtics best offensive player last year. And it wasn't close.
ESPN's Chris Forsberg provides proof of Thomas' offensive impact for the Celtics:
That Thomas is spearheading Boston's offensive attack should come as no surprise. The Celtics owned an offensive rating of 109.2 points per 100 possessions -- the best mark on the team -- when Thomas was on the court after his late-February arrival last season. Boston's rating dipped more than nine points per 100 possessions without him on the court in that span.
So it's not a surprise that early returns from training camp suggest that Isaiah Thomas is the focal point of the offense.
