Mike MLB question

Has anyone noticed this or maybe my game is being weird , But after i had a good freshman year , i started to notice that the O line will no do their assignments and let guys run by just to have the whole o line try and block me . so i have guys on the other side of me by week 5 these guys have like almost ten sacks each. Also ill block shed the guy only to be reblocked by the same guy before i can get by.
