I'll still be rooting for Garcia. This match is designed to make Garcia look promising.
Oscar De La Hoya of the Golden Boy Promotions is the brain behind Garcia's fights, making him as a functional cash cow. This fight though is just an interim while Oscar negotiates Lou DiBella (G. Kambosos Jr's promoter) in the meantime given that Garcia will defeat Tagoe first.
Emmanuel (33 years old) is much more experienced than Garcia though with 33 bouts and 15 of that via KO, so yeah much more lower KO rate than Garcia and unfortunately the latter will just be a stepping stone to the rising star.
As someone who has watched fights of Ryan Garcia on the ring, his explosiveness, accuracy, and long-reach is what makes him an exceptional fighter. Like what you have mentioned, De La Hoya is somehow making Garcia the next 'golden boy' on the ring as he is being promoted every time he fights.
According to boxrec, Emmanuel Tagoe is definitely an experienced fighter on the ring. With 32W (15KOs) and only 1 loss, he is someone that cannot be taken lightly, even if you are Ryan Garcia. Though experience would be key in this match, I do have my bet to Ryan Garcia primarily due to the fact that his punches are more explosive.
