But his brother-in-law and former longtime Miami Dolphins teammate apparently had no problem switching allegiances.
"We had been talking to the Jets as well, and we had the option of waiting even until after the draft or before training camp," Rosenhaus said. "But the truth of the matter is Zach was excited about the chance."
Thomas, like Taylor, spent last season in the NFC East after more than a decade as a fixture on the Dolphins' defense. They combined for 13 Pro Bowls while playing together.
Taylor is waiting to sign. He probably won't have a new employer until after the NFL draft in two weeks, but it almost certainly won't be the Jets based on what he had to say last week.
"It'd be very, very, very difficult. Very difficult," Taylor said at a youth football camp. "But at the end of the day, if you can't find a job anywhere else and the Jets call, I guess you've got to retire or go play.
"The Jets are the Jets. I've had a lot of history saying bad things about Jets fans. The fireman hat guy [Fireman Ed], and all of the people in New York that are Jets fans are not the ones that are working on Wall Street. I've said all of those things. So I've got to leave it at that."
Taylor would appear to have more attractive options than his wife's brother did. Taylor could land with the New England Patriots, a legitimate Super Bowl contender.
The Chiefs went 2-14 last year, but Rosenhaus ticked off a number of reasons Thomas was interested: new general manager Scott Pioli, new head coach Todd Haley, new quarterback Matt Cassel and the fact Thomas likely will be the starter.
"Zach really likes the opportunity in that defense," Rosenhaus said. "They play a 3-4. He's going to get a chance to start inside. He's going to be 36 years old in September. To have an opportunity to start for a quality franchise, you can't turn that own."
