European coaching pioneer Jakob “YamatoCannon” Mebdi has concluded his groundbreaking tenure with LCK squad SANDBOX Gaming, opting against contract renewal after a condensed six-month engagement.
SANDBOX Gaming communicated through official social channels that both parties reached a mutual separation agreement. The organization and coach both referenced personal circumstances influencing YamatoCannon’s choice to depart rather than extend his commitment.
I’ve chosen not to re-sign with @SBGaming_KOR – I will be forever grateful for everything and I will elaborate further in the future. I will keep the memories very close to my heart and I am sure that our paths will align again to finish our story.

Did YamatoCannon Deliver the Anticipated LCK Transformation?
YamatoCannon established himself as an esports trailblazer, becoming the inaugural European head coach recruited by an LCK franchise. Pandemic-related travel complications delayed his physical arrival until the third competitive week of summer competition. Before his onboarding, SANDBOX struggled profoundly with an 0-5 match record and no victories to their name.
Hello fans. This is SANDBOX Gaming.
We have some sad news for you. We have decided to part ways with head coach YamatoCannon who led our team this past season. pic.twitter.com/k5yh4kXmqp— SANDBOX Gaming (@SBGaming_KOR) October 13, 2020
Once YamatoCannon integrated fully with the team, SANDBOX demonstrated marked improvement with multiple consecutive victories. Despite this positive momentum shift, the squad couldn’t secure postseason qualification, concluding the split in seventh position with seven wins against eleven losses. The logistical hurdles preventing YamatoCannon’s timely Korean arrival substantially compromised summer split prospects, though SANDBOX performed considerably better than their spring performance that necessitated relegation tournament participation.
It was great to work together. I wish you happiness!

SANDBOX Strategic Preparation for Franchise Model
The LCK competition structure transitions to a franchise framework in 2021, mirroring LCS and LEC league models, with organizations actively preparing operational adjustments. Riot Games hasn’t finalized which ten franchises will receive LCK slots next competitive season. SANDBOX’s readiness to extend YamatoCannon’s contract potentially indicates confidence in their franchise application success and continued league participation.
While most SANDBOX player contracts extend through 2021, the organization might implement substantial roster modifications before spring competition commences. For teams navigating franchise transitions, understanding optimal team composition strategies becomes increasingly vital for long-term competitive planning.
YamatoCannon hasn’t disclosed his professional direction for 2021. The former head coach currently contributes to the 2020 World Championship broadcasting team as a professional analyst, providing strategic insights during premier international competition coverage.
Action Checklist
- Evaluate coaching impact through both quantitative results and qualitative team development metrics
- Assess cross-regional coaching integration timelines and cultural adaptation requirements
- Review contract structures to accommodate potential travel and logistical complications
- Develop contingency plans for coaching transitions, including interim leadership and candidate pipelines
