Disagree. That is an "If A, then B" statement, where
A : "Tretiak is the greatest of all time"
B: "Patrick Roy is the greatest of all time"
If A is false, then the statement is logically true regardless of the truth value of B. That implication is only false if A is true (because in that case, given the statements involved, B would have to be false).
