I picked Stipe by (T)KO in the second. I don't actually want to see that happen, but I have a really bad feeling about this fight.
While DC is the more technical wrestler and can probably out-wrestle Stipe, it's hard for me to picture him getting close enough to ground him without eating big shots, and with his age it seems almost sadistic to expect his chin to hold up to that. He's repeatedly shown the stubbornness to simply walk through strikes. Aside from that, Stipe is generally pretty disciplined with his jab and maintaining range - I'd say out of everyone DC has faced in the past two years, Stipe probably has the best distance control of them all. He's not going to literally turn his back and run away from DC like Gustafsson did.
So, idk. I like DC, I think him somehow winning this fight would make for a great story, but... I don't think it's likely. If he wins it will almost certainly be decision or RNC.
