I just finished watching tape for the Jeremy Stephens/Doo Ho Choi fight.
Doo Ho Choi is quick and very accurate and is going to have a pretty big advantage with his hands going into the fight with Jeremy Stephens, he will land with his hands. I just don't think Jeremy Stephens has good hands and tends to loads up on his shots and doesn't throw fluid combinations.
The thing that concerns me is how hittable Doo Ho Choi is, he is also vulnerable to leg kicks which he doesn't check very well and right head kicks because he keeps his lead left hand low which works in favour of Jeremy Stephens. It's a 5 round fight, Doo Ho Choi's pressure style of fighting leads him to gassing/slowing down whereas Jeremy Stephens is better at pacing himself. Jeremy Stephens is a big featherweight too, so we could possibly see him going for takedowns too if things aren't going well for him standing up.
I'd really favour Doo Ho Choi if it was 3 round fight but a 5 round fight favours Jeremy Stephens. I do favour Doo Hoo Choi in this fight just because his hands, speed, accuracy are so much better than Jeremy Stephens but other factors like his defensive striking, his pace leading him to slow down especially in a 5 round fight, at best he should only be a -130 favourite, his current line of -170 is too high. Both guys have good chins and if it goes to decision, Doo Ho Choi most likely wins on the scorecards because he will throw and land more volume unless his leg gets chopped down.
