Obviously there would be no need or want for Russell if Kyrie resigns with the C’s, but given recent dysfunction, I wouldn’t be the least bit surprised if Kyrie wants to pull a LeBron and take his talents elsewhere. If it comes to that (which I hope it does not), the free agency pool of point guards isn’t looking too great - unless you want to pay 30 year old Kemba Walker the max. And from what I gather, not a lot of folks here want Rozier back, ecspecially as the starting PG.
I’ve liked Russell since he came in to the league, and he seems to improve every year. It’s not unfathomable to think he could reach an all star level someday. He’s restricted this summer so the Celts would have to bid on him, but he’d be a hell of a lot cheaper than Irving, I would think.
