The Warriors set the template for neutralizing Allen and Mobley. They both have a high center of gravity so the Warriors would get wide and push them off their spots on the floor. This was especially clear when the veteran Warriors knew the play was about to set one of them up. Some of this will be gaining strength, some of this will also be anticipation.
All that said, Mobley was the man in crunch time of a close Knicks game. He owned the glass and scared the Knicks away from scoring in the paint. Julius Randle is in his prime, making bank and on national commercials... but Mobley dominated him all night without Allen's help.
Mobley still finds ways to dominate even if they make it tough on him to get his offense rolling by collapsing on him in the paint, by having strong/low center-of-gravity guys push him around down low, bumping, grabbing, and yes, fouling with impunity. When it came time to grab rebounds in crunch time he dominated with his length, athleticism, and determination. He would not be denied. And defensively he has become almost a force field around the paint, who causes offensive players to pass and defer their shots when they sense he's within blocking range (which is more often than not). Nobody wants to become another victim in part of Mobley's ever-growing highlight reel of blocked shots.
Evan has surpassed my expectations by leaps and bounds already, and I can hardly imagine what he'll bring to the table after his first off-season as a pro getting elite NBA level conditioning and training. Even though Mobley is a slender guy he's still strong as hell. When he adds another 25-30 lbs. of lean muscle he'll be an amazing force in the paint. He'll nail down some signature moves and shots that will become almost automatic, he'll have a few counter-moves to his counter-moves. He'll get more comfortable with his three point shot and he'll start taking more of them. The future is bright with this young man.
