Steelers of the 70's: In their best 5 year stretch they had a .777 winning percentage. The Patriots from 2003 to this season (not including tonights game) have a winning percentage of .822. While they currently have about 3 locks for the HOF, who's to say that doesn't change? Plus, when looking at the Steelers of the 70's everyone gives them credit for Stallworth, but he was just coming on in the late 70's and took off in the 80's. Swann is so overrated...decent receiver, played on some great teams, doesn't deserve to sniff the HOF. His highest yardage total in a season: 880. Most catches in a season: 61. Basically, he has Deion Branch numbers if Deion were to play for 2-3 more seasons.
Similarly, Bradshaw couldn't hold Brady's jockstrap; he threw two fewer interceptions than TDs in his career and has a QB rating of 70.9. His best season (88.0 in 1975) isn't even close to Brady's career rating.
Defense: clearly the Steelers made their name on defense. They were top 5 in either points or yards in 7 out of 8 seasons from '72 until '79. Well guess what...the Pats have been top five (and actually, top TWO) in points our yards 4 out of 5 seasons from 2003 until present. Guess what? The Pats current stretch--ranking-wise--in points allowed goes like this: 1st, 2nd, 17th, 2nd, 1st. The Steelers best stretch in points allowed: 1st, 17th, 1st, 2nd, 2nd. Looks kinda similar, huh?
This isn't to discount the Steel Curtain and all their steroid-enhanced players. They had a great run. But the Pats are having their own great run, during a time when it simply isn't supposed to happen. One common theme with the Steelers was consistency: they had almost no roster turnover year-to-year, they just drafted well and 'developed' (*cough* steroids *cough*) their players better than anyone. The Patriots have had to get rid of some very fine players (Milloy, Law, Branch, among others) and are sure to lose some more (Samuel?, Wilfork?, Seymour?) during the coming years.
Anyway, sorry for the rant. I just think it's ridiculous to think the Steelers are even in the same league as the Patriots...their accomplishments are many and their teams were fantastic, but they didn't have to do it during this era with constant roster turnover, and if anyone wants to start throwing out asterisks, how bout taking a look at the Steelers. You want an unfair advantage, how about shooting your players full of steroids for a few years, see how that goes. Friggin' videotapes of coaches aren't going to give you an advantage like that (if it even gave an advantage, period).
