He had Dorsey.While not a great player due to limited skills, he knew the position,
BQ had a fine mentor.
While Dorsey was smart, he only had one year as a starter (if that), nowhere near the experience that Danielson had as a long time starter in Detroit. The two aren't even close. And throw in the fact that Quinn missed all of TC and the two weren't even in the same universe as far as development as rookies.
