Starting DT Marcus Harrison has 20 total tackles and a sack on the year while back up Anthony Adams has 34 total tackles and 2 sacks so far.  Adams actually began the season starting 5 of the first 6 games then was replaced by Harrison.  Why?  I have no idea.  Every time Adams has a chance to play he gets results.  In the last 5 games all of which saw Harrison starting with Adams in a reserve role, Harrison has 5 tackles and Adams has 19.

The Bears rotate their DT's enough so starting is really just a formality, but I think the most productive players should get the nod on the first team.  The impressive thing about Adams is when he was moved to the bench you didn't hear a peep out of him.  A true professional.

"Anthony Adams played outstanding ball, making tackles, [and] the big fumble recovery was huge for us at the time.  Those guys have both played a lot this year," Smith said. "One guy normally starts, but both of them play a lot. Anthony Adams, he is one guy I can say who really played well from start to finish [Sunday]. We evaluate everything based on that week and we'll do the same this week."
