Openers can work short term. I coached a summer team and we tried it for a few weeks when our rotation was gassed. The bulk guy was fine, but once the opener got hit the pen wore it for days. You might goose a starter’s W/L, but that stat is noisy. If the goal is wins, I’d rather use the ace in the 6th–8th where leverage spikes.Side note, this debate over which stats matter makes me think of skins. I checked https://skinsmonkey.com/blog/best-csgo-stattrak-skins and ended up choosing a budget AWP StatTrak instead of a pricier AK.
