I have watched the whole video and after about 40-50min into the video he starts nitpicking a lot, he doesn't give tenz the benefit of the doubt that he doesn't have a observers radar to work with and honestly he starts rambling a lot about some of the plays that are pretty standard and could have gone either way. Despite that, he actually makes some good points that I agree with.
- TenZ not being on the same page as his teammates in lot of the plays, specially when he's on the entry role. Lack of comms, lack of team chemistry, there could be a lot of reasons behind it but in general it's a fair statement regarding him and SEN in general. For example, when he has the kayO ult he's always going to flash through something hoping that he gets kills and in worst case his teammates gonna revive him but it almost never pans out that way. I feel like in his head he always works on a time limit, if I have my dash popped i need to do this thing, if i have a kayO ult i need to do this thing etc which is fine cz you need to get the best out of your util at the right time but your teammates also need to be on the same page.
- TenZ is either way too passive or way too aggressive. I would say this is also related to him being low on confidence recently. He is either scared to make a play or tries to over compensate by being rash.
- He is not a leader. I have seen somewhere that sacy was saying in a post match interview that the duelists were not vocal on that day. TenZ is a rhythm person. If everything is going well he will ask for things, he will make plays n stuff but if things start to go bad he goes quieter and quieter. That's the reason why it almost always goes downhill for him in a match. Other top duelists might go 1-5 at the beginning but still finish the map strong. TenZ is not that guy, he starts doubting himself and his sens and his setup etc. Most other duelists, you ask them "who is the best player in the world?" and they would reply "I am the fkin best " but tenz wouldn't. He doesn't have that 'I am him' energy.
- He needs individual coaching and for the matter of fact I feel like all of them need individual coaching. That isn't to say they don't understand the game and need basic coaching but they need someone holding their hands and figuring out what's going wrong for them. One of the greatest soccer coach Jose Mourinho once emphasized on individual coaching and said that "If you are not able to coach the big players, you are not able to coach anyone. You are not going to teach Ronaldo how to take a free-kick, you are not going to teach Ibrahimovic how to hold the ball on his chest, you are not going to teach Drogba how to attack the first post and score in the air. You are going to teach them how to play football, in that team.” I feel like that's what made potter have such great success. She made sure all her players complement each other. I can't tell you how many times I have seen sacy just intuitively use his skye flashes to no benefit of the team but then not have them when his team needs it but he's still a world champ!
Despite saying all that, tenz is still a valuable player no doubt. He was one of their best rated players this season and as sideshow have mentioned, the untapped potential in this guy is huge. SEN has already invested a lot in this team and entrusted them with another season so what's stopping them from giving them a coaching staff alongside kaplan that would work in these players' individual improvement. I have read about a top LoL coach in China giving his players individual assignments for their ranked games! Picking their brains on how and why they makes certain decisions, how they react to certain things and knowing these things about each other would massively improve the team chemistry in my opinion.
