Tito can beat both Forrest and Ken.
The "problem" lies in how he matches up with Chuck and Couture. Chuck did wrestling before he did kickboxing. He is damn hard to takedown and has one-hit KO power. Tito has never been one to trade (ie. he is smart...as much as we love Elvis, if he fought more like Tito (sticks to his gameplan) he might have beat Forrest)). Taking down someone like Chuck without setting it up with striking (like Randy does) is too difficult (in general).
Taking down Couture involves using upper-body takedowns coupled with striking and the occasional shot. Exactly what Randy does. Too much similarity, and Randy has good gas as well.
The thing is, Tito is VERY GOOD at submissions. He just doesn't have the "Minotauro" mindset when he fights. He can't fight like Minotauro and take punches from his guard while he goes for the submission. Tito's ability to defeat both Chuck and Couture will depend on his ability to go for the sub WHILE getting HIT and TAKING risks. Tito doesn't like to take risks (fights smart), and that is what is so difficult.
HOWEVER, Chuck AND Randy (after they fight each other), could EASILY lose to a host of fighters out there. There is a lot of parity at the top.
Shogun just won the Pride 205 lbs tournament. He "barely" beat Minotoro in the process. Minotoro has lost to Vlady. Vlady is, arguably, a better wrestler than Randy, but Tito easily outwrestled Randy.
Tito might be able to beat the man who beat the man (ie. say Babalu gets a sub on Couture, Tito could beat Babalu).
Tito is a "top dog" in this game, and just has to wait until the belt holder matches up well against him. Liddell is almost 40 and Couture is over 40. Tito is, what, 30? Under 30 still?
2007 might well be his year...
or Elvis' (in regards to the King's question about other contendors...Forrest and you are both up and comers, so hopefully we see you back (maybe against Bonner?) and you get on a win streak...)
