Set up to fail is a bad way of saying it I guess but does anybody really think when Green hired Wylie he told him, "by the way, I'm going to bench your starting LT, move your starting RG to LG, then to LT. I'm moving Wells to RG and then to LG, and by the way I'm going to release your starting C the day before camp opens to shake up the team."
Wylie may be a lousy OL coach we dont' really have enough to go on because he wasn't with us very long, but he wasn't exactly put in a position to succeed because he inherited an underperforming OL and then it was completely shifted around, reportedly not by him. Everything I hear is that Wylie was extremely bitter about the demotion but bit his tongue so as not to hurt his chances of getting another job.
He of course got hired by Syracuse and their new head coach Greg Robinson, who has long NFL ties. Buffalo's OL coach McNally was quoted in the press release when they hired Wylie as saying Wylie is a workaholic, constantly striving to improve the technique of his guys, a "perfectionist". That may be why he didn't like LJ maybe he thinks LJ doesn't work hard and relies on talent over technique? and that may be why he and Green didn't see eye to eye, Green has always seemed to be about having tough O linemen that will fight you, maybe he and Wylie didn't agree on what was wrong with our OL, Wylie felt they lacked technique, Green felt they were just soft? Who knows.
I had just never heard anything before that suggested Wylie didn't like LJ, if anything I thought LJ was one of the disagreements Wylie had with Green, it appears that's not true. Learn something new every day.
