We're referring to the stat, which is Speed, and as such, it should be capitalized. I'd like to see a single case where "Speed" Isn't used as part of a larger phrase, and in almost all of those cases, Speed is (and should be) capitalized.
arguably, the difference is that when you are referring to Speed EVs you are directly referring to the stat itself. but when you say a Pokemon has high speed, it's a reference to the stat but isn't directly tied to it i.e. the phrase has meaning external to its official Pokemon definition. I think the same case applies for "speed tie" and "speed tier" -- they are both phrases that refer to the Speed stat, but aren't intrinsically tied to it. Rhyperior and Substitute are both Pokemon terms that have no external meaning, so we capitalize them.
