That's a tough one. His three best years, based on metrics, were all with the Expos. 98, 00 and 02. But he won his AL MVP with the Angels. Kind of shows you what going from Montreal to LA will do for exposure. He had three top 3 MVP seasons in LA, despite (based on WAR) being his 4th, 5th and 7th best seasons. His 1st, 2nd, 3rd and 6th were all with Montreal, 13th, 4th, 6th and 24th in MVP voting in those 4 years.
