Rangers may well be some way off where anyone at the club would like them to be, but there can be no question Rohl has instilled more in a busy eight days than his predecessor Russell Martin managed in three months.
Going with a back three for the second game in a row, Rangers looked far more comfortable in defence, and their change in energy is clear.
Players such as Danilo, Nasser Djiga, and Youssef Chermiti have visibly improved in confidence and focus, with the Brazilian now scoring in consecutive games.
The 36-year-old German coach is also not shy in making changes, rotating five from the victory over Kilmarnock and bringing on James Tavernier and Djeidi Gassama at half-time to try to combat Hibs' growing confidence in midfield.
Ultimately they did not create lots of chances, and relied on some wastefulness from Hibs. But there is far more organisation and edge to Rangers already as they move on to a massive League Cup semi-final against Celtic.
A first clean sheet in 25 away games tells you that.
Hibs will rue their struggles in the final third again, because at times they played attractive football and worked the ball through Rangers.
But too often their play broke down around the box, and the two best chances they fashioned in the second-half were glaringly wasted.
That is a bit of a theme this season and one Gray will look to arrest. The head coach brought Miguel Chaiwa on after just 23 minutes to help them in midfield and moved Josh Mulligan out to right wing-back.
His change had the desired effect as his team improved, but it was not enough to keep their 11-month unbeaten home run in the league intact.
