Great post man. As real fight fans know, movement, angles and timing are everything in boxing, and while Floyd is incredibly gifted in all three areas, he'll be facing something he's never seen before with Mac. Floyd will figure it out, but it will take several rounds to do so, and that is where I think Mac can prove to be quite dangerous, in the first 3-4 rounds.
Mac's movement is very different than most MMA fighters. It's not as awkward as a Wonderboy Thompson, but it's still gives fighters a lot of trouble.
He's also great at using different angles, especially when counter punching. Just ask Eddie Alvarez, he didn't even see half those punches coming.
Mac's timing is also incredible as he focuses more on timing and accuracy than loading up and throwing power shots.
I know Conor can bring in who he wants to spar with, but no one will really give him a good look for what he'll be seeing August 26th, but then again maybe father time has caught up to Floyd a bit, b/c sooner or later, it catches up to all of us.
