CBS is sending its top announcing team, Jim Nantz and Phil Simms, to Indianapolis to call the Ravens-Colts game Sunday. The network passed along Simms' thoughts on the matchup:

"Can the Indianapolis defense stand in there and stop Baltimore’s running game? If it does not, it is going to be fast and Peyton Manning is going to get fewer chances with the football. It will be rough for the Indianapolis offense because the Baltimore defense is so good and has had success against them the past couple of years.  The two big story lines by far are to see if Indy’s defense strengthens up and stops the run.  And what will they do against Ray Lewis and everyone else on the defensive side? It is early in season with two teams with 2-2 records, so it’s not make-or-break for either. One thing that really comes to mind about this game -- we just expect the Indianapolis Colts to come out every year and win their 12-or-more games and be the favorite in the AFC.  This year, there is doubt around the league.  And it is real doubt.  People are wondering if this is where the team starts to fall apart and whether they will have to start making major changes going forward in the next few years.  It is a legitimate question.   It always helps to see the team with my own eyes and to study them a little deeper to get a better understanding about them.  That way I also have a better understanding of the long-range prospects.  So there are a lot of questions about the Colts, especially with them playing a team like the Ravens.  If they really play well, then Indianapolis will have answered all these questions.  And, they will be in there for the rest of the year."
