first of all, there is no guarantee that hitting 60% of your bets if you're only betting favorites will yield a flat bet profit. but think about it for a second, even assuming, aruguendo, that it was possible for US to hit at that ridiculous rate (i'd bet everything i have that it is not, by the way), you are risking a ton of money for at best a marginal return- even if there are no odds on favorites in the series (which US plays with regularity), you are barely scraping by at 60%. foolish.
