Does Brock Lesnar have the ability to be UFC heavyweight champ??

i mean Mirs face was bruised up badly from about 15 punches from Lesnar. and since hes been submitted, Lesnar HAS to have learned some defensive moves against ankle and leg locks (his Achilles Heel??). So from the two fights hes had, anyone think hes got the ability to be heavyweight Champ?? and who could stand toe to toe with him??
