Analyzing net rating

I think it's important to ask for clarification while also explaining net rating. I need to mention that the numbers can really depend on sample size and context. If the user's claim is based on hypothetical stats from a simulation, I should ask for their source.

I want to be concise and friendly, so I’ll stick to a few bullet points. It’s key to avoid making false claims and to clarify the difference between on/off plus-minus vs. net rating differences. The context matters!Providing data options

I can start by asking, "Do you want me to check the data source, provide a complete lineup sample, or do a tactical analysis?" It's important to explain net rating as points per 100 possessions, noting that +13.5 is elite while -13.1 is poor. I should clarify that a meaningful sample size usually requires 50-100 possessions, and if it's under 200 minutes, caution is key.

I'll outline how swapping LeBron for Luka could change various aspects like spacing and usage, but since Luka's not with the Lakers, it's likely a hypothetical question. I'll need to ask about the season, dataset, specific lineups, and minutes. I can suggest verifying with a lineup finder, keeping things concise.
