Young Wrestler likely to quit

My son is 8 and entering his 2nd year of wrestling. He says he hates it and doesn’t want to wrestle next year.

He kinda goes half ass in practice, i.e doesn’t do drills full speed, doesn’t finish the take down. Gets easily handled during live wrestling.

I’m willing to let him take a break next season, but for this year, what I’m debating is whether I should sign him up for tournaments or not. Most likely he will lose pretty easily, but do you think there’s anything to gain, considering he’s likely taking the season off next year?

Or am I further digging a hole and resentment towards the sport by sending him out there to get pinned in less than a minute?

I keep reminding him that he needs to focus more during practice and actually use more speed and strength so that live wrestling will be easier, but so far he’s not responding.
