I agree, it is basically dumb. I don't mind Jet being cocky, but I would just like us to be under the radar a bit, overlooked so we can bring the hammer down. I like it when we are overlooked and when everyone is thinking we don't have another run in us.
Players like KG, RR, Jet, PP get a nice big chip on their shoulder that way. I love it when we play like we have something to prove. IE KG in last years playoffs.
I think guarantees in general are pretty stupid, but they're not a big deal either way. Didn't Pietrus "guarantee" a championship last year? That seemed to amount to a whole lot of nothing.
