Allen is probably the best OL of the ten.
Williams could have been top 2, but the unfortunately accident.
Outside Allen, I think the current OL clearly beats of 90's OL?
To me, Tuinei was above average only while TSmith is top 3 LT.
Step was top 5 C but only there for a few years, while TFred is top 2 C.
Newton was top 5 in my view, but Martin is top 2 to me.
Pat Summerall used to talk up Tui in the telecasts and he had some great games but they helped him a lot and he got beat more often than you would like anyway.
Williams was so physically dominant that he would lunge and do a lot of thing you are not supposed to and get away with it most of the time. he got better about it after the injury but it made it that much worse. He manhandled Reggie White who was supposed to be unblockable which gave him the reputation but he could have been better.
Outside of strength, Newton was an average NFL OL athlete. We were a straight ahead lead gap team that played to his strengths so it didn't matter. He has himself admitted that he couldn't do the things out in space our current guys can do. Gogan fits into this category as well.
Stepnoski was consistent and precise but if isolated with larger DT could have problems. It didn't happen often. I thought Donaldson was just as good or even better. He was more of a power player.
Gesek was Newton lite.
Allen was a transcendent player that could play any position and dominate.
Those guys also got to play with Woody, Haley, Sanders, Pup, Norton, etc while the current iteration on defense has trotted out scrubs each year. If Wilber and Church start again this year it will be more of the same.
