There are a lot of things the Kechii cannot do... Quite a few guys in D1 have tons less experience than him and yet do far more.. Maybe they wouldnt have as fast of laptimes in a timeattack situation but chances are that they will be able to obtain higher slip angles and more dynamic drifting than the "drift king" can provide.

Its not really that Kechii is bad or anything, its just that hes old, and he hasnt taken all the new tricks as easilly as the youngins, but his experience is needed in the judging and the commercial side on maintaining D1 as a first class competition. Hes just a little retired as drift king but hes still the founder.
