Well for that matter most players from the 70's would not be so good in todays game...or even make it.
I was more speaking of his height in comparison to todays plays than size and strength...the more I look back at some of these legendary players the more I doubt many would be able to play...
Franco Harris for example, and one of my childhood hero's...I watch old clips and look at how skinny Franco was, he has like regular guy arms, and a somewhat angular body , especially for a back, and his name is synonymous with NFL history and greatness....Jack Lambert was 210 llbs...one of the meanest SOB's ever.
oh well I guess we just chalk it up to evolution .
