For as many pro fighters that come forwards making their head go up and down in a U shape as they step with bended knees; there are the opposition who only throw straight shots at them as they are coming in. Both are ridiculous but both allow the other to get away with it so it continues to be seen.
To counter it practice following the path that their head is going through with angled upper rips or a cross, or even a swing can work at times, if you dont connect on the end of their head movement you will get it as they have to head back to their centreline.Stay light on your feet to head back as they come forward in the same angle pattern then set yourself in.
Other than that its an instant counter or tough it out block and counter.
If you practice short angled steps with your partner you can avoid,set yourself and be following the path their head is taking all in one nice move.
Short angled steps and then full front to rear leg changes can all work well ,gives you room and makes them further commit.
Pivoting your rear foot around your front foot can get your head out of range and puts your front arm right into the mix with power in the move.
The bob and weave for no reason is ridiculous but I think to time or feint someone into a commitment by making them jab or over extend out from their centre line ,to the side then go under it and come up the inside as tey are correcting is the key to doing it right.
Of course if some one can only throw straight shots and hasnt the thought pattern left to mix it up or react in time cause of his fixed stance,stiff legs or cause he is shelled up behind a jab type, then you are going to get away with more bob and weave attacks against those types.(more so if you lightly check his front arm with yours as you go in, then weave through on his reaction)
