ARIZONA STATE — The Sun Devils have a new head coach in Herm Edwards, and it appears they are going with a cleaner jersey. The sleeve stripes are gone, as well as the wordmark on the chest.
ARKANSAS — Some minor changes for the Razorbacks, and it appears they no longer have a matte helmet.
BALL STATE — The Cardinals have a new white jersey for 2018. The numbers have gone from red to black and the TV numbers on the shoulders have been replaced by stripes.
BOSTON COLLEGE — A small tweak for BC that most people probably wouldn't even notice. They have added two vertical stripes to the collar that mimic the sleeves.
CONNECTICUT — UConn is bringing back their block-C helmet logo in both white and blue versions, "for select games."
FLORIDA — The Gators look is mostly the same, but they are the latest school to switch to Nike's Jordan Brand, adding the Jumpman logo to their uniforms.
HOUSTON — It's not clear if any of these are technically new, but with different shells, decals, and facemask colors, the Cougars will have 12 different helmets. They could wear a different one for all 12 regular-season games.

ILLINOIS — The Illini have a new look this season, including their classic orange and a new blue helmet.
INDIANA — The Hoosiers have added sublimated candy stripes to their sleeves and the end of their pants.
IOWA STATE — The Cyclones have added an all-black uniform. They have also dropped the shoulder stripes and appear to no longer have a red chrome helmet.

MISSISSIPPI — Ole Miss now has a white helmet that will be worn with an all-white uniform against Texas Tech.
NEVADA — The Wolf Pack have moved from Nike to Adidas. The new uniforms have ditched some of the stripes and added a new light blue pant which appear to be replacing their white pants. It's also hard to tell, but the helmet might be a tad darker, possibly to match the dark blue jersey.
NC STATE — New uniforms for NC State. It is not clear in these photos, but Tuffy, the school's wolf logo, is on all three helmets. Also, it is difficult to see, but the emblem from the state flag is sublimated on the jerseys, just above the left hip.
OHIO — Small, but significant, change for Ohio as they have moved the shoulder stripes from the top of the shoulders to the sides.
OKLAHOMA — OU is also jumping on the Jordan Brand bandwagon. The new uniforms also come with slight tweaking to the chest lettering and apparently the helmet logo is a little wider. Side-note: Linemen make the Jumpman logo look small.
PURDUE — Does Purdue have a new matte helmet this season? The school posted this photo to social media and it appears to be a new matte gold paint job, although it is possible it is just the lighting or a filter.
SOUTH ALABAMA — The Jaguars have switched from Nike to Adidas although the uniform looks largely the same.
SOUTH FLORIDA — USF has switched to Adidas. They have not provided a complete look yet, but the helmet color looks different and it might even be two-toned, with a darker color towards the bottom.
SOUTHERN MISSISSIPPI — The Golden Eagles are yet another school that made the switch to Adidas this season. Gone from their Riddell jerseys are the off-color sleeves and the outlines on the numbers. The helmets have added two stripes.
TEMPLE — The Owls have added a new grey jersey and all the uniforms have a new striping pattern across the front.
TENNESSEE — There is a rumor that the Vols will be ditching the checkerboard pattern from their helmets and pants. However, during a recent photo shoot, the checkerboard was still there. One change that is coming for the Vols is they have dropped their "smokey grey" alternates. Nothing but orange and white this season.
