Concussions can be very serious injuries. Yes, they are common in football, but sever concussions can cause chronic problems. Regardless of the how good Karsten is as a football player, I think it would be ridiculous not to take his injury seriously. Karsten has worked his ass off to try to make this team better. I'm as frustrated as anybody else with this team, but I have no doubt in my mind that Karsten has put in the necessary time to help this team win each week. I can deal with lesser talent losing games to better teams as long as they give it their all. Don't worry, I'm not related to Kartsen, and I've never talked to the guy in my life. In fact, I was a supporter of Crum at the beginning of the season. Everyone can say what they want about Karsten, but peronsally, I'm glad he is a Poke. He embodies hard work and the American Spirit. I miss that attitude desperately right now.
