They finish each other's sentences, sometimes taking glee while doing so. Sometimes they both start laughing at an inside joke that just flew over your head. The affection between them is obvious.
Not surprising.
As Chris Kluwe says, during the Vikings season he sees Cullen Loeffler more than he sees his wife. Kluwe is the punter and holder for kicks. Loeffler is the team's long snapper. They are football's version of a baseball battery, each dependent on the other for success. They have been NFL teammates since Kluwe's arrival in 2005. So is it any surprise that they kind of sound like an old married couple?
For example: Loeffler was asked about how often the two hung out together.
Loeffler: "Not much. Because he's been Mr. Advocate over here."
Kluwe: "Ah, the political stuff ..."
Loeffler: "See, he's the political sounding board now."
Kluwe: "That's because I don't take time to shoot that many helpless animals."
