Pro Football Hall of Fame coach Mike Ditka had some strong words for former President Barack Obama and San Francisco 49ers quarterback Colin Kaepernick.

In an interview Thursday on "The Bernie and Sid Show" on WABC Radio in New York leading up to the Super Bowl, the legendary coach discussed his support of President Donald Trump and the criticism New England Patriots quarterback Tom Brady has received for not openly doing so.

"I think these people are -- can I say this? -- that they're a-------," Ditka said.

The 1985 Super Bowl champion went on to say that Obama provided "no leadership at all" to America during his eight-year term.

"If he (Trump) can screw it up half as much as Obama, I'll be surprised," Ditka said.

He also shared his thoughts on Kaepernick, who made headlines this NFL season for taking a knee during the national anthem.

"He'd (Kaepernick) be a complete unknown without the game of football. … And not to respect that, you've got to be a pretty unintelligent person," the coach said.
