I think their identity remains a hard nosed competitive team that backs down from nobody. Wade reinvigorated that in Butler/Gibson and then Lopez is a bigger Noah type.
The wings have developing games, and the depth is nice.
With the exception of a healthy Cavs, and maybe a perimeter issue like Toronto, there is nobody who can take us lightly in any form. We added a couple guys with that killer instinct, and Butlers is still developing, its good for him to see and feed from.
We have 4 defensive guards for incredible small ball combos to give teams fits, and we have swing snipers who can play inside and stretch the floor. We are a nightmare for "small ball" teams in my opinion because of the capable center and on ball guards.
Butler/Rondo/Wade/McW are all very bothersome ball defenders with length to bother shots. Cleveland can muscle us up a bit, and present a host of issues to any team.
I'll be curious to witness the form of the team that snuffs us out, because I think it takes some special matchup issues to confidentally dispose of this extremely versatile Bulls team.
