Bynum
Have to say before because of Bynum.  I picked to far down to match the talent and size of a Bynum.
The actual Lakers team has more potential but they're under-performing relative to their talent all season long. 
Judging against potential, I think the actual Lakers win out.
Judging against performance, I think your creation wins out because of Gortat's superior defense + rebounding and Turkoglu's added offensive play. 
Oh wait, Lamar Odom is a big swing factor. That will likely keep the actual Lakers in the lead. Have to wait for that starting PG + bench ... could be close.
