the effect of wrong player position?

Depends on how out of position it is I suppose. A striker in goal or defence would be disastrous.

I spent almost the whole of my third season with an ML in the AML position, he had a high attack rating for my level and he performed as one of my best players that season!

well I put an MC in place of ML or AML sometimes, my only ML is really weak and i have plenty of MCs with higher stats
