Stevenage boss Graham Westley says his Rotherham counterpart Steve Evans does not live up to his fiery billing.
Scot Evans has a reputation for being vociferous on the touchline.
"Steve's an alright guy. People read him as a fiery character. A lot of it's just huff and puff," Westley told BBC Three Counties Radio.
"He's a guy who's willing to smile away from his football and he's got a job to do in the dugout, and he plays with that fire but he's a pussycat really."
Westley's side, one point above the relegation zone, host the play-off chasing Millers on Saturday.
Evans, 51, has twice won promotion from the Conference Premier with Boston and Crawley.
His time with Boston was tarnished after he was given a 12-month suspended jail sentence in 2006 for tax evasion.
"He's a good manager," said Westley. "He did the job in the Conference [with Boston].
"Obviously he had his problems when he won promotion from the Conference and everybody has talked a lot about that.
"But he knows how to get teams winning. He's gone on to do well at Rotherham."
