I think so. Jones won't be used to someone being able to tag him from his engagement range.
I think the big questions are: Will Jones be able to take him down, and hold him long enough to get a sub?
Will Jones be strong enough to get out of Walkers vice grip thai clinch?
If Walker opens with that powerful leg kick it could rattle Jones if he doesn't grab it, or retaliate immediately then I could see Jones go to his wrestling, and try for a submission. If Jones stands with Walker I think this fight will end in short order with Jones waking from a dirt nap.
I think basing opinion on Walker's looses is folly because it was 3 years ago, and he has undoubtedly grown quite a bit as a fighter since then. Basing it on his quality of opponents is also a bit of a folly because we have seen his skills, and one of his flurry's in RD 2/3? IDK was quite long and powerful.
IMO he has top level skills in striking that should worry everyone in the division. If he builds up some TDD he is going to be a handful.
