that could be...and would surprise me.
Spending some money is always reasonable imho, unless all others are bot's ;) You can pick a decent "star" and develop good players too: not all must be at maximum potential! I am very proud of my medium potential players!
I understand your position, but I was told quite frankly (by BB-Forest, if I remember well) that the rationale of the draft is to allow teams having a low record to improve their roster, so basically you shouldn't invest in scouts if you're having a very good season.
Moreover, information provided by scouts is sketchy (what about knowing what's the height of a player? And how come I only know the age of a player if I scout it twice?) and draftees are often so unreasonable that only an unconstrained randomness could have created them (extremely tall PGs or too short Cs), and even if they have some respectable score (players describe with 4 balls, maybe with 3 or 4 balls of potential) they simply cannot even be trained to become a backup in an Italian IV serie... fired or sold for few bucks to someone that ended up firing them in a short time. I was quite lucky in season 4, 5 and 6, but it was pure luck.
I hope your experience is far better than mine, but I don't really expect anything from the draft anymore, since I have very little control of what happens. Maybe if I'm able to pass to III serie I'll throw some money into scouting, but it's just rolling the dices...
