The 10-year veteran never forgot what it was like to play on the NFL's largest stage and came to Chicago for a curtain call.
"I've been talking about Super Bowl since I've got to this team," Muhammad said. "That was the one thing that I came to this team to win a championship and bring a championship to Chicago."
Since the start of mini-camp, each practice ends with the team huddling up and shouting "world champs". While the regiment may not be uncommon from that of any other team in the league, the simple gesture is a step in the right direction.
"In order to believe that you're a championship team you have to start talking about it," Muhammad said. "You have to start believing in yourself, believing in your teammates. It's a mentality and to believe that you're the best and when you go out on the field to play that way."
Each win has the team thinking a little bit bigger. After six straight victories, they're to the point where anything is possible.
"This team has the characteristics of a championship team," Muhammad said. "Do we win a super Bowl? Can we go to a Super Bowl? That remains to be seen but we believe we're a team that can win a Super Bowl. So every Sunday we have to go out and prove that to ourselves and our opponents."
Oddly enough, it appears the team took their largest step forward after two straight losses. The Bears were never in the game with the Bengals because of five interceptions by QB Kyle Orton and lost 24-7, which left them 1-2 heading into the bye.
With two weeks to prepare for the Browns, a road trip to Cleveland seemed like an opportunity to get back on track. The Bears dominated the game, but were only leading 10-6 late in the fourth quarter.
Two big plays in the passing game by the Browns turned the game around and the Bears dropped a 20-10 decision. Even with the disappointing fashion in which they lost, something positive came from the experience.
"The team developed a lot of character in those two loses and we learned how to win games," Muhammad said. "We learned if we don't do certain things we're going to lose but if we do certain things we're going to win close games."
The lesson has been applied as the Bears are on their longest winning streak since 2001, with four of the six games being decided by eight points or less.
