Nancy Reagan - By the end of her life they weren't even hiding the fact she was E.T. and I kind of expected her to leave a trail of reeces pieces wherever she went.
Charles Woodson - Being an NFL DB is probably the most physically demanding position in sports. You don't dominate that position covering 4.3 guys while still tackling 230# guys until the age of 40. I know some folks will chirp in that his play had fallen off A LITTLE. Yeah, he is no longer getting back-to-back-to-back All-Pro teams like he did early in his career..... I'll grant you. Others will point out that Lott also played at a pro-bowl level at both CB and S...... not for nearly 20 years like Woodson did and Lott looked WRECKED at the end of his run. Woodson looks roughly the same as the day he rolled off the cyborg assembly line. Look at his freaking hair line! I'm convinced our future cyborg overlords made him retire simply to stop drawing attention attention to himself. Same reason they forced him to choose to only dominate the NFL on defense, not on defense/special teams/offense like he did at Michigan because it would simply be too conspicuous. Finally, some conspiracy had to be in play to let this "guy" just retire with no fan fare. If you were starting an NFL team today and could have any 20yo player FOR THE ENTIRETY of their career name three guys you would rather have. GO! Jackie Slater..... maybe one of my favorite players ever but didn't even start his first three years in the league so don't come with that type of weak sauce. I will listen to arguments for Bruce Mathews(another clear cyborg btw) but I will take a freakish CB/S over a freakish interior OLman. Can you imagine watching Mathews back pedal in space to cover a modern WR or even TE at the end of his career........ they are barely even the same sport at that point and you may as well be making kicker arguments. Even Brett Favre, how dominant was he in ATL? Anyone addicted to pain killers is obviously a frail human being. From start to finish Woodson was a terror for nearly two decades. Unbelievable. Inhuman.
