And now - why Dooku and Yoda above Windu? Databank And Wookiepedia would answer:
"It was said only two opponents ever bested him -- Yoda, and Dooku."
"Only Masters Yoda and Mace Windu were considered to have fought on equal terms with him."
"It was said that the only opponents with a chance to out spar him were Yoda and Count Dooku. "
"Along with Yoda, Dooku was one of only two Jedi who were known to have bested Mace Windu at sparring, and during the time of the Confederacy Crisis, it was said that aside from Yoda, only Windu would have been his equal on neutral ground." - starwars.wikia.com
So - its a prove.
And something about Kolar:
Mace Windu himself, considered one of the greatest duelists in the Order's history, found Kolar's abilities considerable. The Jedi Council felt that Windu and Kolar alone would provide a significant counter to Darth Sidious were he to reveal himself. - starwars.wikia.com
