goordie, there have been numerous studies on the brains of dead nfl players, almost everytime the conclussion is that they had cte and the brain of someone many years older. i agree that more research needs to be done. BU has requested from the seau family if they can study his brain.
following his suicide many players were wondering if they would be next and started looking for help.
over 1500 former nfl players have now sued the nfl over their concussions and head injuries, with 100 more filing today including former stars like jamal Anderson. its not coincidence that they filed the day after seau died.

here is a good article describing some of the law suits the claims , and what they have to prove

here is another article about former players who are stuggling with memory loss.

the bottom line is that there are literally thousands of former NFL players suffering various levels of brain damage ranging from depression to memory loss to dementia. the suicide rate of ex nfl players is higher then just about any other occupation with the possible exception of pro wrestling (where there are also tons of head injuries)
there is no speculation anymore as to if former nfl players suffer from brain damage, the question is more to what extent are they damaged and to what extent is the nfl liable?
in terms of seau specifically, we don't know yet if he had cte, depression, memory loss or any other brain injuries. we will probably find out more in the near future
