You need more punches in your arsenal. Most all of what you were throwing was 1-2. 1 1 1-2. etc. Always trying to set up your 2. And your jab for the most part was used as more of a rangefinder. Flicking it. This guy had some size on you and it appears power. Having only the 1 and 2 consistently going at him you are open to being countered a lot unless you can work more in there. This guy following you around the ring you need to make a stand somewhere...and I think it may best have been served going inside with flurries...combos, mixing in more body shots that finish up stairs,hooks at the end of your combos etc. You just need to throw more when you do let them go.
