Yeah I even in remember in 2006, the Jays brought in Bengie Molina late in the offseason on a one-year contract and pretty much Zaun was on the bench or played 30-40% of the time. Molina was a slow, high contact, low BB and low K bat with some pop. Zaun at least got on-base at a much higher clip and did have some decent pop. Zaun had a great 2005 season and they still brought in Bengie which IMO was a waste.
Overall, Gregg Zaun was a real solid catcher during his tenure with the Jays. Very underrated with the bat and his defense behind the plate. He caught Doc during his prime as well.
I hope Kirk could end up being like Gregg Zaun, which I think is a fair comparable. They have a similar skillset offensively and Kirk obviously has more power potential. He just needs to keep in better shape.
