Even if you cut out all of the fights, menuing and load times, you can see that it takes way more than 5 minutes to get to REX's husk, even when you know where you're going. If that wasn't bad enough, Samus is in contact with Liquid pretending to be Samus's mentor. He'll lead her astray around the terrain just to waste what precious little time Samus has left. My team is scared of Samus, so much so that their battle plan is based around beating her. They know they can beat her without doing a single thing, so they'll just sit back and wait for her to die. They'll even know exactly when it happens because of Liquid. Samus is a complete non-factor in this fight.

So that means it's BJ and K. Rool vs Metal Gear REX, Cloud, Vivi, and Lu Bu. BJ's in his Chniby phase right now, thinking he's some fantasy swordsman when he's really just a dude with guns. He's going to run out and get himself killed. That leaves K. Rool with a machine gun. REX is more than enough to take him. Snake needed RPGs and Gray Fox's help to down REX. K. Rool isn't doing that by himself with just a machine gun.

TL;DR:
Samus is dead before the teams interact. BJ thinks he's a lot stronger than he is and is going to get beat quickly, and K. Rool can't take my team by himself.
