That would really only be one extra year though, since Pratt is still young enough where they’d stash him early next season to buy the extra Super 2 year and play the service time game (which, who knows what that looks like after the next CBA).
This path definitely comes with more risk, but higher reward. And at the end of the day, 50M in payroll spread out over 8 years or 20 M spread out over 6 won’t make a huge difference.
