question about underdogs

[dochock77]

I have often heard the fact that 80% of teams that win in the NFL end up covering. but i was thinking, if an underdog wins, then of course they will cover.

so the bigger question is what percentage of favorites who win end up covering the spread?

one way to figure that out it is to know the longterm statistical average of what percentage of favorites (or underdogs) actually win (regardless of spread)? anyone know the accepted standard, if there is one?

74.4%

Since 1985, NFL Favorites are 3817-1912-8 SU

Those 3817 winners are 2720-938-159 ATS
