I think it's too early to say. imo Sentinels are winning thanks to sorting role and player issues pretty early on, built team chemistry very quickly and they got a lot of off season matches to happen, so progress-wise they seem at minimum like a couple of months ahead of other teams. They've clearly practiced a lot, but have lots of kinks they need to work out; but i feel like the skill ceiling for them will only grow more. The win will still be deserved considering the work it still took to get even to this point so far.
That being said, the main reason I say that it's too early is because every team progresses at different rates, we are bound to see different teams do well as they sort out their shit. A good player is only as good as his team allows him to be, so there are many many potential promising talents this season that are going to start popping off once things get refitted.
All in all, I'm hyped for the rest of the season regardless. I'm already consistently pulling all nighters to watch these stupid Masters matches.
