Wilner is only saying this because the Jays are linked to Martin. I actually called into Wilner's show last year and mentioned Martin specifically as a target because of pitch framing and Wilner said Navarro was doing a great great job behind the plate and he didn't think the Jays would need to make a change. Also said Martin isn't good offensively.
Wilner just says what is convenient at the time for the Jays and will always say the Jays made a good move, even if it was not a good one.
