I thought this piece was relevant, despite it being about NBA players, it's about recovery time from Achilles ruptures. My takeaway is simple, Opara has at least a year before returning, and he won't be the same guy. He may come back strong, but there are huge hurdles ahead, and the odds aren't that great that he makes it back, at all. A quote from the piece: "they examined 18 players who'd sustained ruptured Achilles tendons between the years of 1992 and 2012. Of those players, seven never returned to play in the NBA, and 11 came back for at least one season. Eight of those 11 returned to the league for multiple seasons... More tellingly, player efficiency rating (PER) dropped by 4.64 the first year back and 4.28 the second. To understand how severe that drop is, consider: This year, a difference of 4.64 PER is the difference between Kobe Bryant and Ersan Ilyasova." This is the full link
