A. He's not going to continue at a PPG pace. I'd be surprised if he tops 60 by the end of the season.
B. Points do drive D salaries, but it's a bit more complicated. Gostisbehere had more points than Heiskanen, Weegar, Carlson etc. last season and didn't clear 3.5M in his contract this season. Pionk isn't a top-pair D with the Jets, and that will factor into his next contract.
C. The cap will likely rise to around 96M in the next 2-3 years. But I think he's been overpaid on his current contract, and I'm not sure that his earning potential has grown now that he's heading into his 30s. Jets have DeMelo, Miller and Salomonsson on the right side, and I think Chevy won't be twisted into overpaying Pionk at an AAV, especially if he gives him a bit longer term. My guess is that Chevy and the Jets see Salomonsson as a future 1-2RD, which will affect how they value Pionk.
But this will be a fascinating negotiation and decision for Chevy. He's been burnt a few times with contracts that he's had to buy out, and I doubt he'll want another strong buy-out candidate.
My post was predicated on the condition that he continues at ~ the same scoring pace as he has so far. The post of yours that I replied to seemed to be making a similar assumption.
Even if his scoring pace drifts back to closer to his normal he might end up with 50-60 pts and his defensive play has been better than usual this year too. I think he would expect at least a similar cap % as he had last time, so 6.5+ mil. I can't see him taking less than 5 years.
Ghost had never had an AAV higher than 4.5 mil before and was already a year older than Pionk will be when his next contract kicks in. He had a reputation for weak defensive play. Much more so than Pionk. He has usually scored a little more than Pionk but I think the bad D rep has hurt his earnings. He has been traded, along with picks to sweeten the deal, for future considerations, traded for a 3rd several years down the road, and allowed to go to FA twice. I don't think he is a good comp to Pionk, despite the scoring.
Having DeMelo, Miller and Salomonsson on the right side, Chevy may not want to offer Pionk enough to get him to extend here. If so, I'm OK with that.
We would need to find a 3RHD pretty soon because Miller probably doesn't have long left. 3rd pair D aren't
too hard to come by, even RHD.
