What Chaotix says is talking sense.
People know you want to go for the overhead, and depending on the player, they can buffer a reversal and react to it easy enough. So you have to pick your spots when using it. Going for option selects/safe jumps/meaty cr LK on their wake up will generally be your safest bet if you know you are in a position to use one. But really, it seems like you are having trouble conditioning your opponents more so than anything else. As well as realizing when you can’t condition your opponent.
If you are constantly getting a reversal uppercut through your dropped link that pretty much means they are mashing it out and your links aren’t tight yet (so get them tight). This usually means they don’t actually know what to do against Dudley when he is in close except mash it out. So start blocking mid string/combo. Personally, I will almost never block mid combo since I can pretty much always hit my links when I hit confirm. But if I am playing online (where combos can drop easy from lag) against someone who mashes through strings, I will often be willing to end a combo early to get a free punish.
When it comes to people mashing out in block strings however, you need to mix up when you block. Normally I start doing this after my first attempt at a jump in. If they block the jump in and and immediately reversal, or if they reversal after the first blocked cr. LP it is clear to me that they will mash through strings. So I change gears to blocking at either of those intervals randomly and often getting a free punish. These sorts of players should become easy to lead around since they basically cannot be conditioned by you. But you can know exactly how they will respond without needing to condition them yourself.
If you run into someone who hits you with a reversal after the second cr. LP or at a later point in your block string, you know that it is an opponent that knows his timings. Which also means that it is probably someone that is not mashing, since it would have hit a reversal during the earlier points in the string. Those people are simply waiting for you to think you can finish your block string comfortably before they reversal at an opportune moment. Dealing with these sorts of players is much more difficult and really requires not just mixing up blocking mid string, but also mixing up your strings so they can’t become too familiar with what you are going for.
I find that if I keep doing cr. lpx2 into kidney blow to keep positioning, people will look to reversal during Kidney Blow’s start up. So if I not only mix up blocking mid block string, but start mixing up my block strings, these sorts of opponents will hopefully become conditioned to second guess the signals that they look for to reversal.
This is where i think Target combos have a good use in Dudley’s game. They can’t be mashed through, often push you back to a safe distance, can be ended early for a mix up, and some can be linked off of as a hit confirm. But I feel like at beginner levels of Dudley play, their usefulness won’t feel quite as apparent.
Sorry for the wall of text. I hope I don’t sound like a crazy person with all this =P
