Yes you can. Tell me the names of the 4 & 5 star defensive players he brought in. We are a thin defense in the middle and the players need some good coaching, that’s not happening for sure!
If he demonstrates a willingness and ability to adapt in a way that makes improvements then he could save his job. But it needs to happen really soon.
I will continue to blame the actual problem, whether that be a coach or players. Perhaps one day you'll get over whatever hangup you have with proper analysis.
