This league is terrible, therefore lots of players stay away. This league plays out of whack, timewise with the rest of the world, therefore, players stay away. This league has some of the worst refereeing I have ever seen, players talk-Players stay away and finally, this league has a salary cap so, players don't want to limit their earning potential, therefore they stay away. The reputation of this league isn't great, players look at it as "Mickey Mouse" and ...stay away
Mo simply cannot get the talent because the talent doesn't want to come here to this third rate league.
There are exceptions, in players such as Robbo and DeRo but for the most part, the talent doesn't come.
So, Mo works with what he can. Carver works with, what he can. Do you really think replacing Mo or Carver will make a difference, especially at this point?
