Unfortunately, the NCAA isn't as image conscious as the NFL. If they were, they'd require full leg covering like the NFL. OK, forget kneepads and pants covering the knees, but at least get the legs covered with long stockings or full length underpants, etc. Another image improvement would be to require jerseys to be long enough to be tucked into the pants, OR, at least require matching color undershirts that are tucked into the pants. No more exposed abdomen skin (belly or back), and no more undershirts hanging out. And, personally, I'd like to see a requirement for jersey or undershirt sleeves to extend down to the elbow. Those exposed upper arms and underarms/armpits are just plain hideous.
This is not an image thing, but, if I was in charge, I'd make it illegal for any player to wear gloves or anything on the hands/fingers, of any kind. Let's get back to the 'natural' ability of players to catch the ball, and let's see those hands on the opponent's jersey, etc., when blocking. If it is cold, just suck it up. OK, belt-worn non-powered hand warmers could be allowed. They don't offer any assistance to the player in playing the game. If you have a broken finger or bone in the hand - just suck it up or sit down.
And, I'd make it an AUTOMATIC foul for a player to give a first-down signal. Geez. They act like they just won the world championship for making a first down.
I doubt you'll see any of that. But we (well, I, anyway) can wish.
Happy New Year!
