You don't follow. If your IGL tells you to go push at the wrong time in a wrong place. You're at a massive disadvantage. The skill differences are very small in pro play, and if you do stupid shit, it doesn't matter how good you are. You're gonna lose.
On T side when m0nesy was on his dry streak it didn't look like he was doing much of anything. Just holding mid window and mouz knew he was there. And he wasn't there because he decided to do so.
If you get into an honest 1v1 and miss your shots that's another story. It's not like they did a lot of that though.
