The B's have gone from 96 pts before Sweeney to 93 pts and now on pace for 88 pts. By the objective standards of actually winning games (which used to be important around here) the team is in worse shape than they were last year (and that was worse than the year before and that was worse than the year before and that was worse than the year before)
The offense is non-existent as the team is 22nd in 5 on 5 goal scoring. The team is not at all resilient (despite spending millions to add great leader David Backes). In fact, they are 28th in the league in goal differential when trailing by 1. COL and ARI and NJ and BUF are all better at getting that tying goal than the Bruins are.
It's nice to have a list of your favorite Sweeney moves, and he has made some good ones, but the ultimate goal is to win. I don't see the team reducing prices for tickets and saying "Hey don't expect us to win until Jacob Zboril can buy a beer", so it's totally fair to say that Sweeney has by objective standards made the current team worse than the one he inherited.
Will the 2021 season be a rousing success? Maybe. But there's no telling that he'll be around to see it.
