Andy Reid could punch his ticket to Canton this weekend … so says Brett Favre, who tells TMZ Sports the Chiefs coach is “certainly” a Hall of Famer with an SB win Sunday.

“He’s one of the great guys and definitely a Hall of Fame coach,” Favre says. “Certainly, if he wins this game.”

Of course, Favre’s biased … Reid was Brett’s QB coach with the Packers in 1997 and 1998 — but Favre clearly thinks the guy is a legendary head man regardless.

“Wherever he’s gone, he’s won,” Favre says. “That’s hard to do.”

As for the one criticism of Reid — aka his lack of a Super Bowl victory — Favre says that shouldn’t weigh in when it comes to people’s opinions of him.

And, why? Favre says Reid’s like Dan Marino and Jim Kelly — who are both considered legends, despite never locking up a Super Bowl win.

Regardless, Favre says he’ll still go to bat for the coach no matter what happens in Miami.

“I don’t think his legacy is solidified by winning this — I think it’s already solidified,” Favre says. “This just adds to it.”
