The West Ham defender would still be at Leeds in another timeline, according to the Scot.
And he believes owner Massimo Cellino isn't to blame for the 22-year-old's exit, either.
Indeed, Evans feels his predecessors at Leeds didn't do a good job of handling Byram.
The Scot told the BBC: "Well, I just think 100 per cent if I had been here earlier Sam Byram would still be in the building.
"It doesn't always fall upon the owner to have those conversations with the player. As a head coach, you should be all over these young kids."
Ultimately, then, Evans is criticising the handling of Byram by previous managers.
He hasn't named names but Uwe Rosler is clearly in the firing line, being Evans' direct predecessor. Neil Redfearn, too, could fall under the microscope here - although the Scot would likely not expand if asked that directly.
Is there another timeline where Byram would have stayed at Leeds instead of moving to West Ham?
Or is this something both Leeds and West Ham fans should simply take with a pinch of salt? A bit of big talk from Evans?
