I think he crossed the line once or twice, perhaps not always deliberately.
I was lucky enough to spend some time with Seve at Crans Montana in I thik it was 1987, as a college player who had qualified to play in the Ebel Masters.
I was friends with Mark James, Howrad Clark and a few others who shared the same teacher Gavin Christie, and I was introduced to the man.
He was kind and generous with his time, many stories he shared, but on the topic of getting under peoples skin on purpose, he was rather hurt at the thought.
But in the Ryder Cup, I would imagine that level of hurt diminished rather quickly in search of a point.
I hold him in the gighest reagrd.
I saw him again two years later at The Open and he walked twenty yards out of his way to come across and say hello and asked me how college was going...a true gentleman.
