Participate in our Power Lunch chats Monday-Friday at 11 a.m. at NewsOK.com/sports On OU receiver Kenny Stills criticizing OSU receiver Justin Blackmon on Twitter: Frankly, I'm not sure why these guys continue to think that what they put on Twitter might not come back to bite them. If they don't have a private account, their comments are public and out there for the world to see. I know that coaches talk to players about being careful. If memory serves me, Bob Stoops or someone in power at OU even had a talking to with Stills earlier this year about Twitter. Stills cooled it for a bit, but now, he's back posting fairly regularly. Here's the thing: I know a lot of people talk about banning players from Twitter. If I'm a coach or AD, I would think really seriously about it. As a member of the media, though, I love it. And not for the scandals. Let me explain. You really get to see better who these players are. What do they think about certain things. What are they interested in outside of their sport. Sometimes, the answer is that they don't care about much else and don't have interesting opinions on much. But sometimes, you find out interesting bits that are telling about their motivation, their personalty, whatever. Twitter has also created more connection between athletes and fans, which is good. So often athletes, especially pro ones, are seen as unreachable. Twitter has changed that for the better. On OSU's record in 2011: I'm saying they lose two games in the regular season, but that would still be an outstanding season. I know expectations are high, and they should be. The Cowboys have a ton of talent coming back. My only hangup with them is the hand they got dealt for Big 12 road games. At Texas. At Texas Tech. At Missouri. At Texas A&M. That is a tough, tough gauntlet of games for any team. On the NFL lockout: I'm hoping soon. It will be sad if we get to the fall and have no NFL OR NBA. Yikes. My feeling is that the NFL starts on time. We may not see all of the scheduled preseason games, but from all the talk that's out there, I'd be surprised if the NFL doesn't have opening day as planned.
