they're soft, they're terrified, they're not driving Humvees (2001 called and wants their car back), they got punched in the mouth, it's too warm (uh, it was like 38 at my house the other night - should I have been at the beach?)
None of that makes a difference in a league full of world class athletes. They're all tough, they'll all 'punch you in the mouth' - it comes down to an effective scheme based on the players you have, injuries, and mostly - players have to make plays. That's it. Make more plays than the other team and you will win. No matter what sissy car you drive. (Maseratis are actually pretty cool looking, I think.)
