Jericho was never on top. Bret, even though he wasn't a "huge" draw..was still on top and had years in the 90s when he was a top10 draw in the world and 2 years where he was the #1 draw in America. this isn't guess it made up facts, this is by actual numbers.
Jericho had like 2 or 3 years when he was a top 10 draw during the early 2000s, but he was never the man. that was off the back of rock and austin.
shyt, in 2002, when he had his title reign, he was for sure below Rock, Austin, HHH, Kurt Angle, Undertaker, HULK fukkING HOGAN, very likely Brock after Summerslam, and probably even RVD. Top 10 draw at any point seems pretty generous to Jericho. Top 15, sure.
You also have to take into consideration that his times as a top guy were as a heel and the whole point was to put over a face (HHH in 2002, Batista in 2008, Punk in 2012). WWE has almost never been a heel territory, and Jericho didn't do a good job of making people care about the faces beating him.
