With the law of supply and demand dictating that even bad quarterbacks have markets, any team with a sentient passer has to be willing to listen to what other teams might think he’s worth.

So while Buccaneers coach Dirk Koetter likes backup Mike Glennon, someone might like him more. And Koetter says as much as it would worry him not having an experienced backup to Jameis Winston, he has to listen.

“I’m on record saying that I think Mike Glennon is a starter in the NFL,” Koetter said, via Roy Cummings of the Tampa Tribune. “I’m a huge Mike Glennon fan. So I’d love to have Mike Glennon on our football team.

“But it’s a business, and if something happens that he’s not with us, well, that’s why we acquired Ryan Griffin last year.’’

Glennon’s entering the fourth and final year of his rookie contract, and he played acceptably well when he had a chance. And the Bucs claimed former Saints third-stringer Griffin last year as cover, since there was chatter about Glennon then. General Manager Jason Licht admitted as much this week.

“It’s out there,’’ Koetter said of trade talks. “We’re just going to have to see how it all plays out. But if the right opportunity presents itself, Jason’s going to have to make a decision.’’

And that decision could be to recoup as much as they can for the 2013 third-rounder, who would only represent a calamity if he had to take the field for the Bucs anyway.
