Pressed today to acknowledge the biggest hitter he’s faced in the NFL, Doug Martin pointed to a Falcons cornerback whose name he didn’t remember.

With a little research, Joe figured out it was Dunta Robinson, who is now on the Kansas City Chiefs.

“We collided many times. I think it was twice. We both knocked each other out that last Atlanta game last season. We both knocked each other out. I forgot who that is,” Martin said.

Robinson left the game with a concussion after colliding with Martin in the first quarter of the season finale. Joe’s going to assume Martin using the term “knocked each other out” means Martin didn’t actually have a concussion and it was just a figure of speech.

After that collision, Martin’s next eight carries before halftime netted just 10 yards. Martin exploded in the second half to finish with 28 carries and 142 yards and a touchdown. (You can catch the full Martin interview from the Ron and Ian show on WDAE-AM below.)
