That is somewhat correct. It appears that he made $470/yr for 2010 and 2011, but in 2012 it was increased to $560, Putting him at an even $1500/month or 18k/yr. Not great, but still a decent amount of money to get from a deadbeat dad. I know it sure would have helped if my deadbeat dad helped me and my 3 siblings that much.
That being said, looking at the CBA, it appears that there is a section that increases benefits in the event of death, with payments going up to $4000/month as of January 1st, 2014, and increasing to $4400 as of Jan 1st, 2018. That falls in line with the numbers I had quoted earlier. Straight from the NFLPA handbook:
"If you die before you begin receiving retirement benefits, your surviving spouse or your children may qualify for a widow’s and surviving children’s death benefit, or your surviving spouse may qualify for a spouse’s preretirement death benefit. The amount of the monthly widow’s and surviving children’s death benefit will be $9,000 for the first 48 months following your death. This benefit then decreases to 50% of your benefit credits, with a minimum of $3,600. (Increasing to $4,000 January 1, 2014)"

So definitely not peanuts....
