This season has the feeling of Kyrie’s last year. There were also a bunch of blown leads that year and a sense that the team just didn’t have what it took to close games.
Ainge and the organization are looking at this from a multi-year vantage point, as opposed to a fan’s which is much more oriented towards instant gratification. If he doesn’t feel like the team is a player away, he’ll let the season progress as is and make more significant changes in the off-season (perhaps dealing Kemba, perhaps filling the TPE). They are a good team but not a contender right now and it’ss far from a certainty that we’ll be buyers at the deadline.
