Just pointing out the obvious...
I don't know but I assume the new changes will be implemented on Friday.
I can only answer for myself about the training and I try to train a Base Offense roster.
No, 10% is not a lot. Let's say it takes you two weeks to pop in Passing, at .5 level per week. In 20 weeks of training you will see 1 less pop. 1 less pop every season. It infuriates me!!! Perhaps it is what you suggest or maybe a smokescreen to take people's minds off the fact that another season begins without the coveted jersey maker.
Once I scored a basket that still makes me laugh.
