I see what you mean. Then perhaps the "committee" should have more credit as Big Ken fits into that category too. One thing I'd say we've benefitted from with Ken is we signed a player who's weaknesses in his game were improbable through good coaching.
The data would have to get that specific for it to be useful I suppose. I can see how could be useful for searching through loads of players from all kinds of leagues you won't have the man power to scout. Don't think anything will ever beat human judgement to spot talent or potential though.
