If that's really want you want to do than go for it!
But if you lose interest in the game don't blame me heh

To me Div II is the division where the competition starts to matter.
In Div III there are still a majority of teams treading water. Managers that half give a crap...that is just not the case here in Div II. Even if they are in last place, they are there for a reason and attempting to do something better with their team.
So it can be frustrating. Me, I'll be lucky to make the playoffs, but if I hadn't suffered some early injuries I would be there easily. But I wasn't going to spend myself out of Div II chasing a playoff berth. Heck, I'm somewhat regretting the players I bought already last week knowing that smallfries is likely tanking. But then again I don' think I want to chance facing a revamped Owls team.
Div II is much more strategic and tactical than Div III. Basically in Div III there are a lot less variables to consider because you only need to worry about what a handful of teams may do.
