The way I see it, this season has sucked about as bad as it can and if fans want to vent, they should vent. Call out the GM. Call out the players, the owner, the hot dog vendor, whoever. It's a frustrating time for some. Being angry is better than being apathetic. When I see threads like this, it just means some fans care. That's not a bad thing.
Now, is Minasian a coward? I have no idea. We're not privy to his conversations with Moreno. But hey... if someone wants to call him out - more power to them. Again, it just shows someone gives a rip.
