Something MMA guys forget though is hand speed, boxers have it, MMA guys DON'T! Those takedowns you talk about come in sooooo slow for a boxer, these guys are built around action/reaction, hand speed and foot speed, agility drills. Look at how Lidell throws a punch and compare it to Tyson, it is literally night and day. Same thing goes for the way these guys go in for a takedown, it would be like slow motion for a Champion Boxer. Tyson lands 1 punch in a 4 ounce glove to a rib and you are out for the night, a head shot, he might kill you, seriously. Watch video of Tyson on ESPN classic when he was a kid,even before he won the title, hand speed was just rediculous.
