The Leeds boss feels people may have lost sight of the fact that the full-back is still only 21.
The 21-year-old, seen by many as one of the brightest full-back prospects in England, has been the subject of unnecessary pressure, according to his coach.
Redfearn feels those at Leeds have taken Byram for granted and forgotten that he is still a young developing player.
The 49-year-old pointed the finger at previous regimes specifically but feels lessons still need to be learned at Elland Road.
“We tend to forget about this with Sam,” Redfearn told reporters at a pre-match press conference on Thursday. “We see this full-back who’s worth all this money, with all this interest in him, but we separate him from the other kids – which is wrong.
“He’s still the same age as [Alex] Mowatt, [Lewis] Cook and [Chris] Dawson. He’s still young. It’s maybe one of those situations where we’ve taken it for granted that he’s Sam Byram.
“We’ve lost sight of the fact that he’s still young and still developing. Perhaps mentally he can’t handle the tag of being this top young full-back yet and we probably haven’t handled his development as well as it could have been handed. I’m talking about previous regimes."
Leeds are winless in eight Championship games but face bottom side Blackpool at 3pm on Saturday afternoon. Surely it's time for an Elland Road win?
