If you are into this kind of thing, ESPN's UniWatch has a run down on the new tweaks to the NFL unis this season. Nothing new from the Hawks except a quick blurb that Tony McDaniel signed with the team partly because of the uniforms.
Another interesting note is that the NFL will seemingly enforce the thigh/knee pad rule which means that players like Richard Sherman will actually have to have pads instead of virtually playing in shorts.
In other uniform news, the Sports Business Journal had a feature article a couple weeks ago on the business side of uniforms. The lead talked about how Pete Carroll thought the Hawks were lethargic during a practice last year and decided to change-up the practice pants to grays. Apparently, this got the team's energy going. Carroll used a blue/grey combination during a pivotal game last year. It was at Carolina,coincidentally, this week's opponent.
It was an interesting look into how and who decides what teams wear. A good example is that the 49ers just have Jim Harbargh decide whereas Carroll, John Schneider and the team's equipment manager have the final say on what the team wears although some key team members have input. For example, this year at Indianapolis, Russell Wilson requested the team wear all white so that it would be easier to see players. Red Bryant, Richard Sherman and Earl Thomas were other players named in the article as those that had a say in the Hawk uni schedule.
