Colts, Falcons, and Bucs have released their new uniforms/logos this year. Still waiting on the Chargers, Rams, Browns and Patriots.
Usually when a team is changing logos or uniforms, if they currently have a classic look, they go more modern and vice versa. I'd expect the Browns to go back to the classic look, the Rams to go modern, the Chargers to go modern and the Pats to go classic. The Falcons seemed to be unable to decide whether they wanted to throwback or keep with the modern look, and it ended up being mismatched.
So far I'd rank them:
Bucs
Colts
Falcons
