To me, its just more of a realist approach. The way the Celtics played the last 3 months certainly opened themselves to criticism and doubt from many Celtics fans. If a Celtics fan had limited expectations of this team yet were pleasantly surprised by postive developments, it shouldn't involved being labeled a "front-runner".
Is it "realist" to:
1) Not say a positive thing about the team all season;
2) Say continually negative things about the team you purportedly bleed for;
3) Pick the team to lose to their biggest rival in 2008 and to the Cavs in 2009;
4) Say the team has no shot of winning against the Heat; and
5) Not show an ounce of excitement about the Paul Pierce game winner or any other Celtics victory, or even acknowledge the series other than cracks about the front office?
I think labeling Simmons a "realist" does a disservice to a lot of other realistic fans who follow this team through thick and thin.
