Has there ever been a situation where an elite athlete has been out of football for three years and has come back and been anywhere close to what he was when he left? Even if he has put the drug problem behind him, which is a huge if, would he be anywhere close to the player he used to be? The 2013 season was a long time ago.
Vick missed 2 years when he was 27 and 28 years old. Took him a year to look decent for two years, but was never the same.
Ricky Williams missed 3 of 4 years and came back to get 1000 yards in his second season back.
Tim Hightower missed three seasons and has been a solid backup the last two seasons 29 and 30 years old.
That's all I got.
Different sport, but MJ took two seasons off to come back to win 72 games and 3 championships.
