Ok. Everyone's ideas have been right on the money!! They are great!! I have a couple more though:

HOF - After so many years of retirement, the HOF elects a few past greats to enshrine...huh? huh?....sounds good....

Also,

Retired Jerseys - When one of your greatest players decides to hang it up, how about making a few exceptions and retire his jersey??

And,

I like the NBA Live theme of purchasing different items. (shoes, practice jerseys, ect...) That's something to look into.

There is a lot more that others have already posted that I thought deserve another showing:

Players diciplined for On/Off the field actions..
More creative end zone dances, ect...
COMPUTER TRADES...How long has this been an issue????
PRACTICE SQUADS/NFL EUROPE...A lot of posts for this one.....

Just my input....
