How about instead of focusing on the solgan that the Cavs choose, lets look at some of the slogans they didnt choose.
"Playoffs!! Cleveland, be ready to be disapointed again." (glad they didnt pick that one)
"Hey Boston, S.O.M.F.D (suck our mother fuc$ing d!cks)" (my favorite)
"Kobe, how does our ass taste?" (cute, but it has been done)
"Lebron, the other white meat" (I dont get this one)
"Playoffs, where our pre-game rituals will be taken to the next level" (dont like this one, think its the wrong focus)
