First of all, nobody is offering Kirk a 10-year contract any time soon, lol. I don't think it's fair to expect him or any catcher for that matter to be able to sustain the workload that he was given to begin the season. Most teams will start their main catcher something like 2/3 games, maybe 3/4 or slightly higher for those rare ones that have proven they can handle the extra workload (JT Realmuto, Yadier Molina, Salvador Perez). Kirk likely falls somewhere below the min. threshold, where he's probably a max 90-100 games catcher, but if his offense rebounds, you can still rest his legs while using him by utilizing the DH spot, as they did in his breakout 2022 where he still appeared in 140 games. Most teams don't have a secondary catcher as good as Danny Jansen, but a lot do have one much better than Brian Serven, who allows you to rest your top catcher while at least getting some value from offense or defense.
