Sorry but I have to disagree. If you're bobbing below a hook, bending at waist or knees is irrelevant (although yes, knees are the correct technique), you are still in a prime position to eat a knee (a long knee, done correctly, can easily extend the length of a punch). That is something that is simply not a consideration in boxing.
In the "perfect" scenario you're "down" when they're at full extension however there are to many variables regarding opponent (and your) speed, tactics (what if you started bobbing but our opponent saw you doing that previously so was just faking to set up a knee) and a myriad other things.
So, in my view, in MT a bob is a higher risk move than a slip. And a bob in MT is a higher risk move than a bob in boxing. Hence why a lot of places focus more on slips than bobs (note "more", not "exclusively")
The same reason I didn't change the original quote from "Bobbing and weaving not as much." to "Bobbing and weaving never.". As yes, it is possible and yes ,it does happen, however there's no denying that bobbing is a higher risk move in MT versus slipping.
In summary:
Is it impossible - No
Does it never happen - No
Is it higher risk than slipping - Yes
Is it higher risk in MT than in boxing - Yes
That's all I was saying.
I'd happily change my mind if you can show me how, in general (i.e. most often), a bob is a lower risk than a slip and a bob in MT is lower risk than a bob in boxing. Please note I'm talking real world and most common scenarios, not "perfect world" (in which case bob or slip is irrelevant as in a perfect world either would result in you never getting hit).
Because that's all I was saying, move risk 1 > move risk 2 and risk of move in sport x > risk of move in sport y. As opposed to move 1 in sport x = impossible.
I don't really disagree with anything you said here. It is effective but, yes, it is higher risk. I disagree a little in the details though, and I'm not sure that comparing a bob and weave (used against hooks) to a slip (used against straight punches) is really relevant. There aren't really situations where you choose between them (although I guess some people do bob and weave jabs and crosses, but I personally don't think it's a good technique).
In my experience, a bob and weave is done so quickly that there is no time to throw the knee, even if the hook was a fake. If you are looking at the opponent's chest (and not his head) you'll only fall for a fake that moves his centre. He can't head-fake you into bobbing and weaving. He would have to shoulder fake a hook, which involves turning the body in a way that isn't ideal to set up a knee. A shoulder fake of a jab, on the other hand, sets up a knee perfectly, but it wouldn't induce a bob and weave reaction (it would induce a slip, a block, a parry, or a step backwards).
I guess it's worth noting that in boxing, I usually double or triple up my bobs and weaves to miss multiple punches in combination, but in MT, I don't, since the risk on the way back (the second weave) is too high.
Have I fallen for fakes on a bob and weave? Yes. Have I every risked a knee? No, not really. What have I risked? a vicious right cross. In boxing, being able to double up bobs and weaves (that can go multiple directions including diagonals, not just a basic left and right) means that it's awfully hard for an opponent to predict exactly where to launch that right cross off the shoulder-fake left hook. In MT, the single bob and weave has more limited ending locations, meaning that if I don't keep my left hand up, I can eat (and have eaten) a vicious right hand.
For that reason, in my personal experience, when the bob and weave is done properly (with the knees while looking at the opponent) in MT, there is no real extra risk at the bottom of the parabola relative to boxing (since you only drop about 6 to 8 inches and you are powering through it with your thighs, it really doesn't take long to come back up), but there is extra risk at the top on the way back up.
One other think that is worth noting is that in boxing, you get some guys (mostly amateurs, but some high-level pros like Ali and Prince Naseem) start bobbing and weaving BEFORE their opponent throws a strike. I don't do this and I'm reasonably certain that this version of bobbing and weaving cannot be brought over to MT.
