Tacko got away with a ton of arm contact all game, much of which was while defending Zion. He's the kind of player that gets off the bus with 3 fouls on him.A college ref buddy of mine disagrees. If you are 7'6" and a 285 pound freak drills you- your arms are going to react. I think that's basic physics.
The problem with the call, Fall was vertical and Zion simply ran into him. That's the first foul on that play. Everything else happened after that offensive foul.
A no call have been better, imo.
Maybe you missed the part where Tacko stepped into Zion on that play as well--he literally left his feet and stepped into Willaimson--it wasn't just his arm contact. Watch it again in slo-mo from the side angle.
