While on paper this is a step up it should be a very comfortable stoppage win for Lynn due to being the much bigger man with more power. Perez is a bantamweight moving up to featherweight where he has little chance of winning. Perez had no power at Bantamweight so he certainly won’t have any at featherweight.
I expect Lynn to win by knockout in four rounds due to being bigger with more power combined with an aggressive style.
