It's a tragedy whenever someone dies at 26 and that's a given, so forgive me from looking at this from a football standpoint.
Gaines Adams was the 4th overall pick in the 2007 draft. He was picked ahead of Adrian Peterson, Patrick Willis, and Darrelle Revis. Things didn't work out for him at all with Tampa, the team that selected him, and he was traded during the 2009 season to the Bears for a second round draft pick. For the Bears, this is a huge blow. Adams did not get on the field hardly at all after being traded, but the word was that the team had big hopes for him in 2010.
His girlfriend found him unresponsive this morning and he was taken to the hospital where he was pronounced dead. An autopsy will be performed but preliminary reports is that the cause of death was a heart attack.
