Does Demeanor Matter?

[justT]

I’ll set the stage with an excerpt from a Doug Flutie interview back when he was QB for the Bills (Paraphrased as best as I remember):

Reporter: You’ve been very outspoken lately about the weaknesses in the Dolphin’s defensive line and how you expect to win on Sunday by exploiting them. The response from Miami’s defensive line was ‘Just wait until Sunday Flutie, just….wait….until…Sunday’.

<pregnant pause>

Reporter: Do you really think it was wise of you to rile them?

Flutie: What are they going to do, are they going to hit me harder? They’re pro’s, they’re already giving 100%.

So back to poker, does demeanor matter? Does a jerk hurt himself with his antics (not implying anything about Flutie), or is everyone already giving their best effort to seperate him from his money?
