Scouting reports still matter..
Regardless, why is Lil Loopers post so stupid if most minor leaguers aren't that good? Just because he said most fail? He's not far off and really the point to his post was that trading Osuna in hopes that the returning prospects (either collectively or individually) produce better value seems like a very high risk, low reward move. Consider the state of our BP and the fact that we have far better trade options.
Different players have different values to teams, we moved Gose for Travis as a lateral move to fill a hole. If a team offered us minor league prospects for Gose, front office might have agreed to it assuming they felt he was a AAAA type player going forward. Whereas it wouldn't be smart to trade Osuna for prospects because we know he's already very valuable to this team, we have few options behind him and we have a surplus of veteran talent that could give us an equal haul. If they really wanted to explore that option, it would be in the offseason after we win our championship and the veterans move on and we get our compensation picks. There is no need or rush to move Osuna unless they plan to rebuild after this season imo.
