Tackling question

There are times in the game, where I have trouble tackling people, and I don't mean people breaking some tackles 1vs1. But I was playing a few hours ago and I had a group tackle on this one guy and he broke a 6-man tackle. I think maybe that one was a glitch, just a random thing, but i noticed that there are times that I just have a hard time laying down a hit. Any suggestions?

i had the same problem its the angle u make the tackle at the guy. also the 6 man tackle, the pro tac, idk sometimes they break out of it its happened to me before

good running backs can break out of gang tackles,so that wasnt a glitch
