they had two aoe stuns the enemy had one aoe stun and a single target fear so no...
First Jax stun is only melee ranged and is automatically applied at the end of 1.5 seconds meaning its easy to avoid.
Second Cass Stun is an ult that turns into a slow if you turn away as well as she was most likely bot for the duration of the game which would then take her out of the equation for top.
Third they had a Sona ult that will AoE stun no matter what. A Nocturn fear as well a global ult. A shyvana ult (not sure how to classify it...perhaps a knock into ult?).
Ultimately what it seems to have come down to is there team had Twich and the other team had a stronger comp of map control.
