Aldridge could be a nice fit in the Dallas offense considering Portland essentially runs the same style with LMA in the Dirk Nowitzki role. It’s no coincidence since Blazers coach Terry Stotts was a long-time assistant for Rick Carlisle in Dallas. Once Dirk retires, Aldridge’s takeover would be seamless, and he could play the 5 until that time. But he won’t give you on D what Jordan can.
Actually, you could argue his fit into the Mavs offense would he smooth, too, since he plays similarly to Tyson Chandler and his picking-and-rolling and rim-diving ways work well inside Carlisle’s schemes. Think back to all the guys who play that style for Dallas (Brandan Wright, too). They tend to do well.
Who knows who the better fit would be? Heck, who knows if either one even ends up a Mav? It appears the safe bet would be to assume both of those guys will return to their current teams, but anything is possible in free agency. We’ll just have to wait until July to find out for sure.
