Okay, he did win two TdF's and one WCRR but he never became the same? That doesn't really make sense to me.
He was basically “good” for four months total after his accident. These months happened to coincide with 1989 TDF and WC and 1990 TDF. Try looking for any real results other than that in the second part of his career.
Even then, he was not climbing in 1989 as he had in 1986 and he wasn’t TTing in 1990 as he had previously.
Also, if you listen to any of the multiple interviews he has given on the subject, you will find that I am simply repeating what he has said countless times.
It’s a small miracle that he won the races he did after the shooting accident. However, it also only underlines what his career would have been without it (and the arrival of EPO). And that second part is a great loss, I believe.
