I agree that we need defensive stoppers, but I think we'd be better off looking for defensive stoppers to add to a core of Amar'e, Melo, and Felton as opposed to just Ray Felt and STAT.
We still don't have that "who you gonna let get theirs?" dynamic. Like a Gasol & Kobe, Pierce or KG (when the trade first took place), Duncan, Parker, or Ginobli?
Right now it's too easy for teams to either let STAT get his and stop everyone else, or double and triple team him and force everyone else to beat us. That second scenario only works in our favor when multiple people are on their game...both Chandler and Gallo.
I think we have to stop looking at this team like the rebuilding effort is finished...it's not. We're not at the stage where we need to add pieces here and there...we still don't have a team that can weather a 7-game series against the upper echelon teams. I know folks are in love with the roster because we're finally winning...but this team isn't as good as the Magic that lost in the finals 2 years ago, or even the 3-seed Hawks team last year.
Regular season wins do not always translate into playoff wins, what we need to do is stop trying to figure out how we can bolster our winning total this year to be a 5th seed, and focus on what'll make us a top 4 seeded team and championship contender in 2011, 2012, 2013, 2014, 2015, etc.
