I gave you the answer in post #54.... Learn your foot work. Learn your jab. Change levels with the grappler, throw the jab and step off at an angle... keep him at range.
This is mostly boxing 101..... Why do you think boxers are not taught this? They are.... with one exception.... Don't back out straight, or pull straight back. Even a boxer will step with you and hit you hard if you pull straight back. Grapplers can shoot much further than boxers.... so you will be caught by pulling straight back.
Use your foot work to keep distance, change levels and throw single jabs, then pivot and step out on an angle. Use this approach to set up your bigger punches.
One thing you should learn by watching MMA is that you need to make the other guy play your game... not the other way around. When a pure grappler tries to learn striking for a few months to out strike a really good striker.... the striker makes the grappler look silly. Same when a pure striker tries to learn a few months of grappling to fight an elite grappler. That's because they are trying to defeat at master at his own game... with a few months of practice. If an elite striker can keep it a striking match with the elite grappler... the striker wins. If the elite grappler can make the elite striker grapple.... the grappler wins.
The secret to making the other guy fight your fight is the same for grappler and striker.... learn your foot work. Practice your foot work. Learning your distance and angles paired with good foot work is what will keep you on your feet striking or get you into grappling range to effect your take down.
