He was also noted to be physically stronger than an incarnation of Bane who was the most heavily muscled cortosis miner on apatros even without force augmentation, and said incarnation of Bane also floored one of the stronger students at the academy with the force of one of his strikes (given that this was a year before they were Sith Masters, it's likely this student was at least Jedi knight level). This is again further reaffirmed by Sirak physically overpowering this incarnation of Bane while he was holding back.
Ezra may very well be above Sirak as of Season three, but thus far such a notion hasn't really been substantiated.
The problem with this is that the value of the ranking of Jedi & Sith is greatly different across different era’s, so I’m not sure how you’re going to use that to effectively compare Sirak’s and Ezra’s dueling capabilities.
This is also applicable for the Inquisitors Ezra’s faced in the past season of Rebels. We know that the Grand Inquisitor has mastered all seven lightsaber forms and is a master of the saberstaff while the other Inquisitors (7th Sister, 5th Brother and 8th Brother) are all masters of the saberstaff as well (or at least employ the saberstaff like Sirak). Combine that with the fact that Ezra went toe-to-toe with these Inquisitors (he didn’t really fight the Grand Inquisitor but Kanan did and Ezra sparred evenly with him already by the end of Season 2) and his general improvement towards Season 3 and I doubt that Sirak’s technical skill will present a problem in this fight.
Ezra has fought with the 5th Brother, someone who has matched/overpowered Zeb in a direct physical contest, even blocking a blow from him in which he channeled his full strength (and he even had some momentum thus effectively amplifying the amount of power he could unleash on Ezra). Why is this impressive? Well Zeb had casually lifted up Stormtroopers and thrown them around with physical strength alone, he also opened blast doors with his physical power. Again, I doubt that Sirak’s strength is going to be an important factor for Ezra.
In the end I think that Sirak’s best (and only) shot at defeating Ezra is through straight up outdueling him, however seeing as how his technical mastery of lightsaber combat isn’t going to be a problem for Ezra (given the latter’s own experience with fighting saberstaff wielding opponents) It will probably come down to raw skill with a blade in which I, at this point, don’t really have an idea to compare them.
