LEC 2027 Roster Shuffle: GIANTX Bids Farewell to Jackies for Team Heretics While Mithy Returns to Coach G2 Esports
The European League of Legends offseason has hit top gear with a series of interconnected roster and coaching moves. Within hours of each other, GIANTX officially bid farewell to Czech midlane prodigy Adam "Jackies" Jeřábek ahead of his expected move to Team Heretics, while the Spanish organization simultaneously announced the departure of assistant coach Alfonso "Mithy" Aguirre Rodríguez, who is set to take over as Head Coach of G2 Esports for the 2027 LEC season.
After Three Years with GIANTX, Jackies Steps Up as Team Heretics' New Midlaner
Having debuted in the European top flight at the start of 2024 under the newly formed GIANTX banner, Adam "Jackies" Jeřábek quickly established himself as the centerpiece of the British-Spanish organization. Crowned Rookie of the Year in his inaugural campaign, the 20-year-old Czech midlaner carried his squad to back-to-back fourth-place finishes in the LEC during the 2026 season. Although GIANTX pushed hard to secure him on a multi-year contract extension, Jackies ultimately declined the offer to pursue a new challenge.
According to reports from Sheep Esports, Jackies reached a verbal agreement with Team Heretics to headline their 2027 roster rebuild. In Berlin, he will reunite with South Korean support Yoon "Jun" Se-jun, who is also making the switch from GIANTX. Coached by Erlend "Nukeduck" Holm, Heretics has assembled a high-ceiling starting five where Jackies will form an explosive mid-jungle duo with former Fnatic jungler Iván "Razork" Martín, alongside botlaner Byeon "Hype" Jeong-hyeon and a topside anchored by Tracyn's contract extension through 2028.

Thayger Set to Replace ISMA as GIANTX Rebuilds Around Feisty and Myrwn
Losing both their franchise midlaner and starting support forced GIANTX into a full structural overhaul under head coach André "Guilhoto" Pereira. To fill the midlane void left by Jackies, the organization has reportedly secured South Korean talent Jeong "Feisty" Seong-hoon, who returns to the European circuit following a stint with Brazilian side LØS.
The shake-up also extends to the jungle role with the departure of Belgian player Ismaïl "ISMA" Boualem. To succeed him in 2027, GIANTX has reached a verbal agreement with Spanish jungler Francisco "Thayger" Mazo Sánchez. Coming off a standout 2026 campaign with French LFL powerhouse Galions, where he claimed both the EMEA Masters Spring trophy (along with Finals MVP honors) and the LFL Summer title, Thayger accepted GIANTX's formal offer after holding tryouts with Team Vitality and SK Gaming. He is expected to line up alongside former Movistar KOI toplaner Álex "Myrwn" Villarejo and former Solary support Kim "Piero" Jung-hun.
Mithy Leaves Team Heretics to Become Head Coach of G2 Esports
The coaching carousel delivered an equally significant shockwave. Shortly after GIANTX's farewell announcement, Team Heretics confirmed the departure of Alfonso "Mithy" Aguirre Rodríguez. After serving as Assistant Coach throughout the 2026 season, the 31-year-old Spanish tactician opted to move on despite preliminary extension talks with Heretics and interest from North American franchises including Shopify Rebellion.
As reported by Sheep Esports, Mithy has reached a verbal agreement to become the new Head Coach of G2 Esports for the 2027 LEC season, stepping in to replace Luka "Perkz" Perković following G2's exit at Worlds 2026. The move marks a historic homecoming nearly a decade in the making: between 2016 and 2017, Mithy helped build G2's original European dynasty by winning three consecutive EU LCS titles as their starting support. His appointment caps off a targeted offseason restructuring in Berlin, highlighted by Mikyx's return to G2 Esports alongside Hans Sama in the botlane.
The Strategist's Take
On paper, this three-way domino effect reshapes the entire European power balance heading into 2027. By pairing Jackies' mechanical explosiveness with Razork's relentless early-game tempo and Jun's playmaking vision control, Team Heretics finally has a core capable of dictating skirmishes in the first fifteen minutes. Jackies provides the exact carry threat Heretics lacked when trying to convert early map pressure into clean best-of-five victories.
For G2 Esports, handing the tactical clipboard to Mithy is arguably their sharpest move of the offseason. After the turbulence that ended the Perkz coaching experiment, bringing back a veteran mind known for wave-management discipline, macro structure, and existing synergy with Caps and Mikyx restores immediate stability. While losing a homegrown star like Jackies stings for GIANTX, betting on Thayger's momentum alongside Myrwn's creative champion pool shows Guilhoto has no intention of playing it safe.
