Maybe I'm just too hyped up now since something actually happened, but yes, I think the addition of Nash without giving up our two biggest assets changes everything. Worst-case scenario: We keep Bynum and Pau and fill out the roster. Sounds bad, but come on, we were close against OKC. If we had Nash this year instead of Sessions who offered nothing, I think we would've easily taken OKC despite the problems of our twin towers. Even in this worst-case scenario though, I think Nash has enough respect around the league that he can convince some actual impact players to come to us for our mini-MLE and veteran's minimum signings.
Take last year's team, replace Sessions with Nash, replace Barnes with Hill, and add another ring-chasing veteran who can still play to our bench. I really think that's enough to put us on the same level as OKC and Miami.
But we now have the option to even more dramatically change the dynamics of this team by trading Pau and Drew in moves that fit Nash better. Bynum for Dwight. Pau in a three team trade with ATL that gets us Smith. Starting line-up of Nash, Kobe, Hill, Smith, Dwight. That could be a hell of a team.
