I don't think we can really make an assessment until after FA. And luckily we'll have that luxury since Pritchard isn't eligible to sign that extension until October.
There are a lot of Pritchard-like players available this FA and it remains to be seen how much they'll be paid. As I said before, I wouldn't be surprised if we hedge our bets and try to lock down one of those guards, like: Simons, Sexton, Coby White, even Grimes at the MLE.
If all of those guys easily clear the MLE, then I will say that Pritchard is good value at $22M/yr, but if those guys are struggling to get paid because smaller scoring guards are becoming less important, then I would hesitate to extend him.
And if we do lock in one of those guards, I would still gauge Pritchard's value since he will be less important for our team specifically moving forward. I'm a Pritchard fan and hope he remains a Celtic for a long time, but I'm sure the teams that signed guards like Poole, Quickley, and Simons to big deals haven't exactly been happy with their investment.
