Tips on how to beat Eras Dom?

I’m close to getting TMac & the free hidden gems diamond but I’ve been up by 15+ on the 72 knicks & 85 bucks and blew both games. Feels like when I get a decent lead the cpu turn on god mode and run insane plays and don’t miss. I’ve only beat 3 era squads and im ready to give up on TD already honestly smh
