Tuhia he tomokanga mō tēnei whārangi - I tīmata a Theodore i tana mahi hākinakina iti ki te Rōpū Hockey Iti o Aldergrove, i te wā i whakatūria ai ia hei kaitākaro tino nui i roto i te hītori o te tīma. Ko tana mahi angitu iti i riro i a ia he kowhiringa i te 2010 WHL Bantam Draft, na te Seattle Thunderbirds. I a ia e noho ana ki te kapa, ko Theodore te rangatira me te whakataetae mo Team Canada i nga whakataetae o te ao. I riro i a ia te mētara koura i te 2013 IIHF World U18 Championships me te 2015 World Junior Ice Hockey Championships
me te mētara hiriwa i te 2019 IIHF World Championship.
