The 20-year-old, on loan from Yorkshire rivals Huddersfield, has endured a difficult start to his Bantams career, having conceded 15 goals in seven starts.
Nonetheless, McCall is convinced the youngster is slowly winning over his critics.
He told the Bradford Telegraph and Argus: "Football is all about confidence. Whether it's strikers, midfield players, wide men, they all thrive on it and it's no different with your goalkeeper.
"It was important we played him (Easty) again on Tuesday after his clean sheet against Torquay. People might have thought we'd give Jonny (McLaughlin) a game but the continuity is important.
"Hopefully after a clean sheet last week and then another good performance at Rochdale, Easty will now go from strength to strength."
