So if you don't give Mo any credit, you are releaving Mo of any accountability when it comes to this signing as well right?. That doesn't make sense. He's the Director of Operations, if a signing doesn't work out, you can't possibly blame JDG or Jimmy for finding the guy, you blame the guy who signed him or the coach who doesn't know how to play him (which is typically much harder to prove).
To me, these are signs of a typical signing where a player refers another player, scout checks him out, coach trials him and wants him, GM signs him. If this is the way this worked out, then everyone did their job.
If Mo is actually listening to Preki and he's brining in players Preki wants then isn't he doing his job? would you propose he instead not listen to the coach and sign players the coach doesn't want to work with?
