Maybe the casual fans
All the hardcore fans knew strikeforce had talent
It affects the hardcores, as well as the fighters.
Major media outlets might just throw a token champ from another promotion into the Top 10 rankings, even when that org is actually loaded with talent.
To make it to the Top 10, you gotta beat guys that are considered on the fringes of the Top 10, which can only happen in the UFC.
Hardcores often pretend they are doing some kind of scientific analysis of proof when they use "Top 10 wins" as a barometer for how well a fighter's career has gone. This is the most incredibly stupid way to analyze a great fighter's accomplishments, and it even fails to show what top competition was (and the defense of anything else being "revisionist history" is equally idiotic).
Because of the aforementioned situation, wins over guys like top fighters outside of the UFC (the outstanding group of SF fighters, the excellent WEC 155 fighters) meant less than beating a supposed Top 10 fighter in the UFC.
A win over guys like "Top 10" fighters like Evan Dunham, Dan Hardy, Patrick Cote (MW), or Brendan Schaub winds up supposedly being more significant than wins over the outstanding fighters in other organizations (that weren't Top 10, but proved that they were Top 10 all along later on).
"OMG, HE'S FIGHTING TOP COMPETITION", LOL.
Even WITHIN an organization, guys like Dan Hardy or Michael Bisping can get easier matchups and rise to ranking prominence while guys like Condit, Rory, etc, end up fighting each other and other super tough matchups outside the supposed Top 10.
Hell, look what Brock did to get a title shot. Now go look at what JDS did to earn a title shot. Brock was ranked higher than JDS when Brock had the belt, while JDS had some amazing wins on his resume.
The UFC LW division, before the WEC merger, and before the SF fighters came in, is the best example of rankings BS.
People found it laughable that the WEC 155'ers be compared to UFC Top 10 LW. Whoever was champ (Varner, then Benson) got the token #10 slot.
And it wasn't even just these orgs, there were several other outstanding LW fighters floating in other organizations.
I'm not trying to discredit BJ, GSP, or Anderson in any way, so don't make it about that.
This is about Luke's very legit point.
