the worst thing about the NFL

i have adjudicated  that my my biggest beef with the NFL is perfectly illustrated by this article right here.  the NFL needs a rookie salary cap worse than anything.  I know these kids work hard, but its that, their kids; and it's the NFL.  it irks me that they have not at all implicated some sort of salary restriction for at least the first year of a rookie's contract.  it's sickening how much money the veterans make already, more every year, bigger contracts every year.  but the rookies, and this guaranteed money.  the teams need to just all come together and say they are not going to give rookies this much money, if the league will not do anything about it.  if you can explain to me a good reason to give a kid this much GUARANTEED money, i'm open for suggestions.  although this is probably my biggest problem with the NFL, the whole concussion thing and the care that hasn't been taken of some of the retired NFL players comes in a close 2nd.
