It's just smart football move.
You just can't lock in 9.2mil on a guy who has struggled to stay healthy/not been a force since his rookie year.
He'll still get a shot at being a long term guy here this year, but now we aren't forced to roll into 2022 with Smith, UFA LVE and unknowns.
If healthy and back to his rookie self, he would fit into any scheme in this league, so I doubt Quinn wouldn't love a healthy LVE. Just that we haven't seen that in some time and we can't be held hostage by that any longer.
