All I'm saying is that the stat-line scouting of collective numbers like you mentioned points out obvious flaws, of which I'm not disputing. But strictly looking at those and basing an opinion on that doesn't take into account the context of said numbers or the individual output of certain players vs journeyman gas-cans and roster fillers. It's important to dive into the individuals that are most likely to help the club, and I believe there are a fair amount of interesting options that are in the lower minors.
Like others have mentioned, as it stands right I'd put them in the bottom third of systems. We'll see if that's altered any post-deadline. I don't disagree that the system is still lacking, but I wouldn't define it as trash either.
