The thing is that Conor is an excellent counter striker, and some would say even better at it than pressuring. I don't think someone who pressured him back would have a lot of success for that reason alone. However, if he keeps pressuring as well, instead of stepping back and countering, then obviously it becomes more of a game of chins.
Something to consider though is all of his best counters are against guys lunging in at him from too far away. He gets all the credit in the world for drawing those guys in, but it's unknown whether or not he can counter intelligent pressure. Someone who knows he wants to throw the counter left, and is ready to counter that counter.
