There have always been upsets. Thanks for the soliloquy thoughWrong...again..
Parity doesn't always have to mean a win.
I know you have a spelling bee you're practicing for in the 8th grade but trust me when I tell you there is an enormous amount of parity in college football.
Before 1973 there were zero scholarship limitations.
1973 they came up with 105
1978 reduced to 95
1993 reduced to 85 which brings us to present day
Prior to 1973 a school could have 155 players (and some did)
You can't reduce scholarships by 70 players in some cases and it not do anything
There have always been elite teams and always will be.
It's the next rung down that you see upsets that never happened before or really just a huge freak occurrence.
Add in the transfer portal and the days of just showing up to play are long gone.
The favorite can no show up and win.
If a team has a bad game...the Marshall or App state play perfect...upsets will happen. Add in the portal and parity is the highest It's ever been
