That is the bold opinion of one seasoned Chicago Bulls beat writer.
Mike North, who has reported on the team across all media forms for over twenty years, believes Thibodeau has performed miracles with this Bulls lineup that even the great Phil Jackson would not have been able to pull off.
And the man who now hosts a morning radio show for Fox Sports radio, as well as contributing to the Daily Herald newspaper wasn't mixing his words:
"First of all I think he's (Thibodeau) the best Bulls coach we've ever had.
"I don't think Phil Jackson would have this team going 9-1," he explained from his Daily Herald office.
The radio host then went on to label Jackson as someone capable of handling big name stars such as Jordan, but wasn't so sure he would have been able to mould the current Bulls roster into a winning side.
And North wasn't finished there.
He also picked the Bulls to provide the biggest challenge to the Heat for the Eastern Conference title, arguing the Indiana Pacers were not capable of beating the Chicago franchise come playoff time.
Thibodeau has certainly created a strong winning mentality amongst the Bulls after a difficult start to the season, but with Jackson having coached the Bulls to six championships during his tenure I think it might be a little (very) premature to start talking of Thibs as the greatest Bulls coach ever.
He has some way to go before he can claim that title.
The bulls are currently 33-27 after an impressive run of form since new year.
