Considering the fact the Bobcats were in the Top 10 in scoring defense, defense might not be the biggest factor. What the Bobcats need is another big man because right now its Okafor, Diaw as the main producers with Diop and Howard coming off the bench. If the Bobcats got another big man that could score down low coming off the bench, it would be huge to take the load off of Diaw and Okafor.
That's what I was referring to, a big guy down low who can dominate defensively with rebounds and shot blocks and produce in the paint. I think Felton should definitely stay, and he and DJ will only continue to get better. Unfortunately the franchise was set back with the Sam Vincent season but we are back in the right direction. Though if Alexis fills out and produces, then my point is moot. But yeah, like everyone has stated, a SG who could come off the bench and score would be great.
