It's a weird move but Atlanta likes to make a splash night 1 of the draft.
Honestly, not feeling bad for ol' Kirk. Guy has made a ton of money including $100M from Atlanta guaranteed. He gets that no matter what. Plus with the investment they made in him I'd say he's got 2 years in Atlanta. By that time he's 37 and likely at the end of the road anyway.
Not only that but he is 35 and coming off serious injury. No telling of he's going to be the same.
