To be able to “circumvent” Riot Games, T1 implemented “fire fighting” by appointing Coach Sky to a position in the squad.
Recently, T1 announced a new point in the lineup from the second leg of the LCK Spring 2023. Accordingly, coach “Sky” Kim Ha-neul will take the position of a substitute player of the T1 squad. According to the share from Coach Becker, this move is to legalize Riot’s competition rules in the 2023 season.

“According to Riot’s international competition rules (MSI and Worlds), each participating team must register at least one substitute player. This player must have an official contract and be registered for at least one round of the tournament. Domestic League of Legends.
Currently, T1 has a roster of 5 regular players and 4 coaches without any substitutes. Everyone is working hard every day with the ultimate goal of becoming the best League of Legends team in the world. Therefore, with the agreement of Head Coach Bengi as well as Coach Sky personally, we will register this coach as a substitute player with the nickname Skyyy. This is to ensure that T1 can smoothly participate in MSI, in case the team wins a ticket,” explained T1 Becker.

According to the latest information updated from the LCK, Sky will take the position of the mid lane substitute. However, these are actually just changes in terms of documents to meet the requirements of Riot, and all specific jobs will remain unchanged.
In addition, the move to use the “immutable” lineup during the season, not recruiting anyone else shows T1’s confidence with the starting lineup this season.
