i think siyar will win a decision. howard has better wrestling, but not good enough wrestling to keep siyar down for long. howard will just tire himself out if he tries to wrestle for too long.
howard has a good enough chin to not get knocked out. siyar will be able to utilize his striking game to control the fight. this fight will be a good one for sure. both have power. siyar better respect howard's hands or he might get handled.
