Young's deal is worth $9 million per Tom Pelissero of USA Today and features a $2 million signing bonus and $3.95 million in total guaranteed money.
The former N.C. State standout has six sacks in his career, including three last year as a starting pass rusher for the Lions.
He's a nice fit in Chicago, where he can do some damage as a 4-3 rush end.
Of course, Chicago also lost Julius Peppers when they cut the veteran end because of his mammoth cap hit.
Peppers production wasn't huge last year, but those are still farily big of shoes to fill. Fortunately for the new Chicago duo, there's no where to go but up for the Bears defense in 2014.
