I don't see any of these guys as LOB -- none of them will be Hall of Famers and you could argue all 3 of Sherman, Thomas and Chancellor could be in HoF. Kam probably has the longest shot but if he becomes a coach and is half as good as a leader on the field then he might have a shot that way too. Griffin is good, Flowers looks promising, and McDougald is having a great season (so far) but none of them are even close to the original 3. I don't think TT will even be on the team in 2 years which I know will be an unpopular opinion but I'm just not impressed by him.
They might be good as a unit for a year or 2 but I don't think they will ever come even close to the LOB domination. I believe the LOB was a once in a fan's lifetime group of players so my preference is to not try and compare the crop of youngsters.
