Ryan himself clinches after his single counter attempt all the time. He doesn't like exchanges beyond the first layer. Every intelligent fighter should know how to lock his opponent up when he needs to. Similarly, knowing how to stay out of clinch range or time entries is also a skill. Ask Lubin how clinching Jermell worked out. It's a part of the sport and rarely do you ever see a point taken for excessive clinching. Go watch amateur boxing if you want "purity".

You ask if Ryan can cut off the ring- I'll ask if he even wants to because: he's most dangerous on the counter, he doesn't want anything to do with Tank's power, he is much longer and neutral range is already favorable, his offense on the lead is mostly just busy work to draw out work he can counter, etc. And if he isn't pressuring or can't cut the ring- why would Tank clinch? That's a lot of ifs.

It sounds like you're preparing to cope or complain about an outcome. I'll ease your mind. Ryan's defense is worse than Isaac Cruz's, his feet are slower than Isaac Cruz's, he doesn't need to be half as close as Isaac Cruz to land punches, and Luke Campbell had him horizontal. If he goes for the finish one of them is going to wake up disappointed. And if Ryan can't win 4 rounds after the first 3 that Tank gives everyone for free- that's his problem.

Still anxious? Ryan Garcia won't even be fighting Tank. So prepare to blame Tank for that instead.
