It certainly is a better team than trading Rondo for some picks and then expect everything to fit right in its place like it did for Indiana and OKC.
With Rondo back in his shape, Hayward is a good spot-up shooter and he already worked very well with Brad, Deng is an all star player, good shooter and a lockdown defender and Cousins is already one of the best centers in the league. Hot heads can be cooled off but you can't teach his skill.
