When you’re asking someone to back up their claim with cold hard facts, of course it’s perfectly reasonable.
If you were talking about one or two players, or one or two stats, then I’d agree, but we’re talking about a range of stats of a large group of players from only their first 3 seasons over a 10 year period ... nah, it’s kinda ridiculous to ask someone to collate all that here when any one of you can just go click on a freely available stats site easy as pie.
