Q: Do you think Chris Johnson will beat the record of the most rushing yards?
— Dale Austin, Clarksville, Tenn.

A: I would say it’s a long shot that Johnson beats the record Eric Dickerson set in 1984. Dickerson ran for 2,105 yards that season. Johnson is on pace to run for 2,012 yards.

He would have to average 149 yards per game over his last four games to tie the record. The Titans have games remaining against running defenses that rank 28th (Rams), 14 (Dolphins), 21st (Chargers) and 13th (Seahawks).

Q: Hey Dan, do you think there’s any way the Cardinals reach the Super Bowl again? They looked mighty good against the Vikings.
— Casey D., Phoenix

A: I think we all have probably been guilty of underestimating the Cardinals. If they stay healthy, they certainly will have a chance to get hot late just like they did last year.

And I think we can make the argument that the Cardinals of 2009 have the potential to finish up a stronger team than the Cardinals of 2010, given the way they have run the ball better and better as the season has gone on.

There has been a lot of talk about what an interesting matchup the Colts and Saints might be in the Super Bowl, but a Colts and Cardinals Super Bowl also would be interesting. And an NFC Championship game pitting the Cardinals and Saints could be quite a shootout as well.

Q: Who do you think will be the leading candidate to replace Raheem Morris in Tampa? I know he has not been fired yet ... but barring a miracle turnaround, the season ticket holders will demand it.
— John Klopfer, Ocala, Fla.

A: First, let me say this: I will be surprised if Morris gets bounced after one season. But if he does get bounced, I would suspect he will be replaced by a big name coach.

Usually when an owner makes a move, he looks for a successor who is radically different from the person he is firing. And of course we have seen the Glazer family go after big names in the past, so it’s kind of their modus operandi. We all know the big names who are available: Bill Cowher, Mike Shanahan and Mike Holmgren lead most lists.

Q: Now that all the attention on Brandon Marshall’s discontent has died down and he’s playing well, what are the chances he stays with the Broncos next season? We’d love to keep him.
— Terry Jackson, Eaton, Colo.

A: I think you probably will keep him, Terry. Marshall is a potential difference maker, and it’s not smart to allow potential difference makers to walk out the door without getting any compensation in return.

At least with Jay Cutler, the Broncos received Kyle Orton and a bounty of draft picks. I would bet that if the Broncos can’t sign Marshall, they’ll tag him.
