You can only fairly evaluate somone's legacy after he's done. Then you can look back at his entire career and weigh the impact of, say, Watergate against the significance of the opening to China. As late as 1999, Bob Gansler's legacy would've been some begrudging respect for getting that US group to Italy and having success in the A-League. Sampson - whatever else he may be right now - is certainly not done. It's way too early to identify his legacy.
