I love Perk, will always love Perk, and believe a big chunk of what this team has been missing in recent years related back to his not being around. We missed that attitude and those elbows, we missed having someone around who would make LeBron and Wade think twice about driving the lane.
BUT... I think we've got a pretty close facsimile sitting on the bench right now in Darko. Darko can be that same type of player. If we continue to have issues with our interior D, I'd love to see him get a few minutes at the 5 and see what happens.
Perk may or may not be significantly better than Darko, but I an sure than Perk isn't $6M better - and that's to say nothing of Bradley, an absolute sparkplug who had a tangible impact on the team's performance, and who is still very young with lots of room for further improvement (hell, just look at how much better he got between year 1 and 2!)
