Madison Square Garden has a Mixed Martial Arts (MMA) Octagon in it. The zombie apocalypse occurred in 2010 and the State of New York did not allow MMA fights at the time, only doing so in 2016, 6 years after the end of civilization.
Correction: It would have been easy enough for the Croat's people to bring an MMA ring into the arena from somewhere else. Or simply just build their own.

Maggie, Amaia and Tommaso move a very heavy fuel tank in front of a door to keep walkers out, as soon as they get it in front of the door it starts to move and tip from the walkers banging on the door. A fuel tank heavy enough that three people who are fit and strong could barely move it, would not be able to be knocked around so easily by a few rotting corpses with barely any flesh left pushing against it. In fact with how narrow the door and hallway is, and how heavy the tank is, there is no way enough walkers could push against the tank to move it enough for the door to open.
In the subway tunnel everyone is walking super quietly so as to not disturb the dormant walkers laying in the walkway, they just sneak past the walkers and leave them alive. It would have made more sense to quietly stab them as they went along, especially since several people in the group have long bladed or sharpened weapons, they could have went first and put the walkers down as they walked. That way if someone accidentally makes noise to wake them up, there's fewer to deal with. Plus if they need to come back this way, they won't have to worry about being super quiet and slow again, especially since there's a decent chance of being pursued by the Croat's men.
