Ill give you most talented group since 2013, but going all the way back to 2006 and 2007 is a big stretch. Ill cheat a little and count players like Greg Ellis, Demarcus Ware, and Anthony Spencer as DEs in the 4-3 vs the 3-4. Would a combo of Lawrence and Gregory be a more talented group of des? Then compare interior guys Jay Ratliff, Jason Hatcher, Marcus Spears, Chris Canty, Stepehen Bowen to our current rotation. Jay Ratliff and Hatcher were pro bowl players. Marcus Spears was a solid starter, Canty, and Bowen were good rotational guys that went on to start many games for other teams.
I just dont see how even with Lawrence and Gregory in the fold to start the season this would be even remotely close to the best line in 10 years.
