The Gers missed the chance to restore their three-point advantage at the top of the table, despite coming from behind to lead at the hour mark.
Gerrard’s men started brightly in the capital but Hibs’ opener was entirely preventable and it prompted the visitors to lose their way for a 20-minute period prior to Morelos’ equaliser.
After the break, Rangers were reinvigorated and dominated possession, going ahead in the 57th minute and creating several more chances in quick succession.
None were converted, though, and more slackness allowed the hosts a route back into the game, which eventually petered out into a draw.
There are plenty of excuses that can be made for the result.
Hibs were overly physical and referee, Don Robertson, allowed them to get away with more than he should have. Even more importantly, the assistant referee failed to see Martin Boyle straying offside in the build-up to Doidge’s equaliser.
Gerrard can also point to the profligacy of his players. Alfredo Morelos missed a glorious opportunity in the tenth minute and in the second half, Ryan Kent, Filip Helander and Scott Arfield all squandered clear openings.
The manager has to take his fair share of the blame for this one, though, after his bizarre decision to haul off Ianis Hagi with 15 minutes remaining.
The Romania international had been the standout for the away side in the second half and is the most creative player in Gerrard’s squad.
Hagi did brilliantly to set up Arfield’s goal, played a stunning pass to create Kent’s golden chance and stung the palms of Marciano with a dipping effort from range just prior to the equaliser.
The logic behind bringing on a striker in pursuit of a winner was sound but Gerrard needed Hagi on the pitch if Morelos and Defoe were to get the service they needed in the dying embers of the game.
By that point, Glen Kamara was far more expendable. The Finland international could have made way for Defoe, with Scott Arfield dropping back to cover in midfield and Hagi still afforded the freedom to roam and create.
The second and final change of the game just made matters worse, with Itten, Morelos and Defoe all taking up central positions in the final minutes and nobody willing or able to provide the kind of subtly in and around the box that Hagi offers.
Rangers missed the injured Kemar Roofe on Sunday and while many things went against them during the game, a poor substitution call played a big part in rendering them largely toothless in the closing stages.
