The Hibs Left Centre Back (Hanlon I think) had to pick up Kamara. He couldn't leave him for Doig as that would have then allowed Tavernier free reign down Hibs' left flank.
Hibs back 5 were all occupied: Boyle was picking up Barisic, McGinn had Morelos, Porteous had Arfield, Hanlon had Kamara and Doig had to cover Tavernier had he came forward. That left Hagi spare on Gogic's side of Midfield. I appreciate what you saY about needing help from his defenders, but they were all occupied leaving Gogic to deal with Hagi which he missed.
Anyway, I feel this has went down a bit of a rabbit hole. Like you said, you (and others) have their opinion on Gogic, I have mine. I'll not take up anymore of your time on the matter haha.
