Kent Carlsson had a huge grunt, reverse kicking serves, roundarm passing shots, deadly lobs and dropshots, but 5 knee operations on the left knee before he was 22 and he retired. He made #8 in the world in 1988 and was on the way up, then the injuries continued.
He first hurt his knee at Indian Wells, so no it's not only Rebound Ace that allegedly causes injuries.
He know races horses.
I remember Carlsson defenting Emilio Sánchez-Vicario both in Hilversum and in Kithbuel -needless to say i watched it on TV- , and also, winning in Barcelona, in four sets against a young Muster. He was like a human backboard, in addition to the aforemention.
