Simply put, Franklin is in a lot of trouble in this rematch.
Franklin's game is his strength and conditioning, but he uses his standup as a conduit to use those skills. He's not a guy like Tito Ortiz, who uses his ground and pound to utilize his strength, but as many know he wants to give the fans a knockout. That's going to run him into a lot of problems versus Silva, because Silva is leaps and bounds ahead of Franklin in the standup game (In my opinion, of course). For all the fights Franklin has won for being a muscle bound giant of a MW, it does nothing but put him in slow motion when compared to a fluid and quick fighter like Silva. If they stay on their feet, Silva is going to pick him apart and eat him for breakfast.
Because of that, I think Franklin is going to look back to the Lutter fight and hope to mirror some of what Travis did. That is, take Silva down, out wrestle him, and ground and pound. Franklin has to get Silva down, never stop pounding on him, and try to obtain full mount or side mount. If he can get Silva in a position like that, he's got a good shot of using his size and strength to hold him there and beat on him.
If that backfires, than as crazy as it sounds, I'd take Silva back into the clinch and try to imitate what Randy did recently versus Gonzaga. I know that's nearly insane considering their first match up, but I'd try my best to get Silva pinned in chest-to-chest, hold him to the fence, and dirty box him. Throw elbows, shoulder butts, short punches, whatever you can tuck in their to cut him up and hurt him. What Franklin can't do is leave enough room for Silva to have a hay day with his knees. He has to get Anderson on the fence and mash him there.
If Rich can't score a takedown and then get full or side mount, or can't hold Anderson to the fence, he's going to get mutilated yet again. Personally, I don't see either happening considering how well Anderson moves and how slick he can be on the ground, but Franklin has a shot at winning in those ways whereas anything else is pretty much a death sentence.
