How do you counter a straight right hand?

Holy ****, I remember this vid, had no idea it was him

 

slip to the outside and lead uppercut also works well against the southpaw jab ala JMM

 

Slip to the outside, left hook to the body followed by left hook to the head. Or slip to the inside, jab under his cross, and follow with a cross of your own.

 

If you can anticipate it, take half a step back, hit them with a right uppercut under it then a left hook over it, both to the head

 

these.
Shoulder roll the **** out of his right and then come back with your own!
