Not Zach, nor Lawler, nor nobody else is going to accept less pay if they keep winning and make it to the GC game. How would Walters justify offering them less for doing their jobs to the standard they agreed to? If they missed the playoffs, he might have a legitimate case.
As for Lawler, last night was likely his peak career performance, not to be counted on or repeated next week or on any other date going forward. The stars aligned perfectly for a spectacular one night show of highwire thrills, I doubt he ever has another game were fortune shines as brightly upon him as it did last night, and I hope both he and Zach are aware of that. Some very good things only happen once, Matt Dunigan knows.
