RUSH: Okay, folks, I want you to keep an eye on it. This represents the sea change in the National Football League. The retirement of linebacker Chris Borland of the 49ers represents — this is big — of all the things that have happened with concussions and everything, this is the biggest. I’m not going to lead with this today, but I wanted to put it out there…

Great to have you, Rush Limbaugh, the Excellence in Broadcasting Network and the Limbaugh Institute for Advanced Conservative Studies…

Chris Borland quit the 49ers after one year because it’s just too dangerous and just a little too risky, shoulder injuries, in college, by the way. That’s not being discussed.

But, anyway, I just want to give you a heads-up on this, because I, your host, way back, December 14, 2011, predicted that this trend was going to increase and end up being enhanced, and this is the big one. I mean, this one shocked a lot of people in the league. He’s a star. He just played his rookie year last year. The world is, or was, his oyster in terms of the NFL.
