I came into the Indianapolis Colts-Tampa Bay Buccaneers game with a few preconceived notions.

First, I thought if the Buccaneers were up by two or more scores that the game would be over. I didn't think it was possible to comeback against that ferocious Bucs defense. So, when the Colts fell behind by 21 points, I assumed Colts' coach Tony Dungy's birthday was going to be ruined.

Surprising Undefeated teams

On Sunday, the 5-0 Indianapolis Colts will host the 4-0 Carolina Panthers in a matchup of unexpected undefeated teams, and it should be a good one. At the beginning of the season, no one would've guessed the Panthers, Colts, Minnesota Vikings and Kansas City Chiefs would all be undefeated this deep in the season. In fact, if before the season, if you asked me to pick four teams that would be undefeated, exactly none of these four would've been on my list. But each of these unbeatens need to be wary. Just because you start out 4-0 or 5-0 doesn't necessarily mean you're a lock for the playoffs. There's still a lot of football to be played and teams with similar starts have missed the playoffs in the past.

Second, I thought it was going to be a low-scoring game. Prior to facing the Colts, the Bucs had given up only 7.3 points per game this season. The Bucs defense was so dominating, through three games they still hadn't given up a touchdown pass. I didn't believe the Colts' high-powered offense would be able to get started, especially without RB Edgerrin James.

But that's why we play the game!

I was proven wrong on both counts by a great Colts team. They were getting their butts kicked all over the place in the first half, but persevered and pulled out a great victory.

A lot of the credit in this win must go to Dungy. He kept his team patient despite a first half plagued by penalties, bad play and just plain weird plays.

At one point the Colts intercepted a pass only to fumble the return and watch the Bucs scoop it up and take it to the house. But despite the setbacks, they chipped away and got themselves back into the game. Then in the fourth quarter, the Colts managed to put up 28 points against the No. 1 defense in the league.

Unbelievable!

The Bucs' injuries did help fuel the Colts comeback. Starting left cornerback Brian Kelly was injured in the first half, which left backup Tim Wansley to cover Marvin Harrison. Harrison abused Wansley so much the Bucs had to move starting free safety Dwight Smith to cornerback to slow him down.

That's when the Colts' offense started to hit a rhythm and switched to a shotgun formation with Manning calling the plays at the line. That move forced the Bucs' defensive line to go a little further to pressure Manning and they weren't able to get any rest.

The officials also played a role in the outcome of this game. One of the turning points of the game was when the officials gave the 2-minute warning with 2:04 on the clock and then gave a second 2-minute warning after the next play. At the time, the Colts only had one timeout left but were essentially given a free one.

The second came at the end of overtime when an illegal leaping penalty was called on Simeon Rice, while Colts' kicker Mike Vanderjagt was missing the potential game winning field goal.

Contrary to what some people may think, Rice wasn't called for the penalty for being helped in the air by a teammate. As the videotape clearly showed, that wasn't the case.

He was called for landing on a teammate while coming down. This rule was setup to discourage players from recklessly jumping in the air, landing on their teammates and potentially causing a serious injury. This was obviously not the intent of Rice, who had a player blocked into him, but the refs have to call what they see.

If the penalty hadn't been called the Bucs would have had the ball with just under four minutes left and 40-yards away from putting kicker Martin Grammatica in position to pull out the win.

Instead the Colts were given 15 yards and a 29-yard attempt for Vanderjagt to win the game. That may have sounded easier than it ended up being!

The kick was low and Ellis Wyms was able to tip the kick and alter it enough that it hit the goal posts before going through the uprights.

That bizarre ending was a heckova way to end the greatest comeback I've ever seen and probably one of the best games I've ever seen.
