Simply because of inactivity. He knocked Veit down in the first round and you were just waiting for him to finish it but it just didn't happen, he suddenly got lazy and didn't do much for the rest of the fight.
Did you see Braehmers last fight against Velazco? Don't get fooled just because he KOed this glassjaw, known as Veit, who nearly went down in the first round after being hit with a double jab. Braehmer would lose to Inkin and Bute. He would beat Berrio though, unless he fights as uncautious as he did against Velazco, then he would get KTFO.
Brähmer would beat Inkin, I'm thinking that his stamina has improved and he has by far the faster hands...and both ain't no defensive geniuses
