Yeah, John can likely solo both rounds. Strong enough to easily beat the ever loving crap out of both Dex and Fisk simultaneously, and he should be fast enough (especially if he is at bullet-dodging, double-dose level) to take avoiding action against anything Dex might throw. And considering he can take pointblank small arms fire with only minor damage, and even survive a bomb detonating in the palm of his hand, he can probably tank most of what he gets hit with anyway.

Haven't seen Season 3 of DD yet and haven't watched all of IF Season 2. That being said, Bushmaster is big screen MCU material, and thus he should win the day for team 2.
Both Dex and Fisk are pretty formidable in DD s3, but still nowhere near the level needed to take on a guy who can hang with Luke Cage in a fist fight. Davos really isn't needed much here.
