Somebody can correct me if I'm wrong about NFL pensions, but if he plays in three regular season games next year he will be eligible for a pension at age 55 of around 1,400/month in today's dollars. Namely, not adjusted for inflation between when he plays next year and his age 55 (or after). If he makes a roster and sticks four years without ever playing a down, he will receive an additional annuity of $435 X years on roster a month at age 55. So for 4 years he would get $1,740/month and this is adjusted for inflation annually (I think). The two amounts combine. Maybe not a big deal, but $20K a year might help TA live a better life in retirement and is a heck of a pension for four years work. Not only that, but minimum salary is $465 K, which would be $1.8 M over 4 years. If he put some of that in a 401K, which the NFL matches $2 for every $1 put in (up to a point), it could be a sweet gig if you ask me, even if he warms the bench for 4 years.
Money aside, the man is what Nebraska is all about even if he routinely made me crazy and I hope he makes it in the League.
