i was reading something not too long ago about michael bennett being/having olympic speed.
portis is probably the best now.
without a doubt, in my opinion, bo jackson was the best...ever. man, if he didn't get hurt, i think he would have re-wrote the record books and the raiders would have won a lot more games in the 90's. i watched many, many games of his - i remember once against the lions, he turned the corner and just took off. a DB was just able to knock him out of bounds...bo ran over one of the lion's coaches - i was CONVINCED he killed him - it was like a deer standing in front of a train (little old guy, too). obviously he lived, but - man - bo was something the NFL may have never seen after jim brown and won't see again for another 30 years.
...another reason to hate the bungles...
