Michael Femia makes the case:

... The kids aren't really getting better. The timeouts and substitutions still make no sense. Scalabrine is still getting minutes. Pierce is starting to mail it in. Wally Szczerbiak gives you all of Antoine Walker's negative (shaky defense, indefensible 3-pointers, driving into triple teams) with none of Antoine's positives (hustle, obvious desire). This team's on a treadmill, and something needs to give. ...

Michael Gee begs to differ:

Firing a coach/manager during the season is the last refuge of the clueless. Small wonder Celtics' fans should be the ones calling for their team to do so. ...
