Yes, that was one of the worst, if not the worst, NFL game broadcasts I experienced.
I understand it was a Bears' broadcast but when the Bills were on defense they rarely announced who made the tackle. They conducted interviews while the Bills were on offense. Unless I missed it, they didn't give the Bills' starting lineups.
Sam Rosen is a national broadcaster so I would've expected better. However, if he was getting nothing on the Bilsl from his spotter, it was a production issue.
There was one running play where Bell pushed Urlacher into the secondary.
