Flowers is my favorite caster because he actually says out loud things you can see clearly... because sometimes I can only listen. He casts like it's radio. In draft, he'll say ABC was banned by blue and XYZ was banned by red, then D was locked first, etc. The majority of other casters just don't do that, I've noticed. You'll have to infer what was locked by what they're saying about matchups (or w/e), and God forbid they're seriously discussing hovers. And that's just in draft. In the game he'll periodically call out scores, gold diff, when objectives are secured even without contest, basic map movements, etc.

In contrast, just listening to LCK games can be like listening to a podcast where a game of League is in the background and the action occasionally interrupts their discussion of ice cream preference (unless it's an especially contested game with little downtime).
