Seems to me that he's the realistic guy who will be traded and bring back a like vet SG. Who might that be? PHX is heavy on guards and are looking to move Bledsoe or Knight. I think to obtain something like that we would have to move some combination of Gay, Koufos and Ben.
Might have to set our sights a bit lower but I'd be going after Bledsoe if possible.
It would be great if we could get Eric Bledsoe. He's a borderline all star PG. A 20+ PPG type scorer, with decent play making ability, and is a very good defensive player. I think he would be an ideal running mate for Cousins, and if we could keep Rudy Gay in any deal (doubtful), that would be a decent "big three" to build around.
Who is going to play backup C?
Here is our current roster:
PG: Collison / Cousins (rookie)
SG: McLemore / Richardson (rookie) / Bogdanovic (if he comes over)
SF: Gay / Casspi / Butler
PF: WCS / Labissiere (rookie)
C: Cousins / Koufos / Papagiannis (rookie)
Now in terms of who we could consider trading to find an upgrade at PG or SG, we are probably looking at Collison, McLemore, and Koufos as our most tradable players. I don't think we will want to give up Rudy Gay unless of course we end up receiving someone like Eric Bledsoe in the deal who would give us an upgrade at PG, a 20+ ppg player, and an ideal running partner for Cousins. But in an ideal world we can keep hold of Rudy and land a new starting PG who can form a "big three" with Gay and Cousins, and use defensively orientated players at SG and PF who can perhaps shoot the three.
But to answer your question, who is the back up center if we trade Koufos? As it stands, Papa, but we would also be able to go out into free agency and look at signing a mid-tier free agent center: Roy Hibbert, Timofey Mozgov, Marreese Speights, Ian Mahinmi, Zaza Pachulia, and Miles Plumlee. Granted we may want to keep Koufos, but he is a tradable asset and if we want to keep the likes of WCS, we may have to bite the bullet and trade Koufos and accept signing a mid-tier free agent center, or end up using Papa and WCS in the center rotation when Cousins is off the court.
I didn't say it was a great idea. I'm not really sold on KK as much as others . My bigger concern is who plays SF if we trade Gay.
Let's say a hypothetical trade occurs where we lose Rudy Gay and Ben McLemore but gain Eric Bledsoe. That would give us a legitimate upgrade at PG and leave us with:
PG: Bledsoe / Collison / Cousins (rookie)
SG: ? / Richardson (rookie) / Bogdanovic (if he comes over)
SF: ? / Casspi / Butler
PF: WCS / Labissiere (rookie)
C: Cousins / Koufos / Papagiannis (rookie)
Two holes to fill. Now I'm not sure how we stand cap wise at this point but I think we should have enough wiggle room to get two decent starting players like Courtney Lee and Luol Deng. They are capable shooters and defensive players who could slot nicely into our line up. Obviously if we had the cap space we could look at Barnes, Parsons, or Batum as possible starting SFs, but we could use free agency to fill that position. I appreciate that losing Rudy Gay leaves a void at SF, but if we fill the PG position with a borderline all star like Bledsoe, we are simply filling one void (starting PG) and opening another (starting SF). The question is, are there more capable stop gap SFs or PGs? From the free agent list, I think we could fill the SF with a better and more useful player than some of the journey PGs.
