This one is bound to be controversial, but there’s a lot to be said for Condit conceding takedowns against St-Pierre. Scrambling a bit, making him work and then willingly going to his back might be the best way to win a ground fight, given the tools at his disposal.
Condit is known for aggression off his back, while St-Pierre is known for putting guys wherever he wants to in the cage. Condit won’t be able to fully defend the takedowns, so he might as well let the fight go somewhere in the cage where he can win instead of contesting it somewhere in between.
On the feet, Condit can win. Despite GSP’s stellar submission defense, he can win off his back as well.
Where Condit can’t win is with St-Pierre in on his legs, ragdolling him and slamming him around with repeated power doubles.
If Condit finds that he can’t make his man work adequately for a takedown—work enough to maybe give that knee some aches and pains—he’s better off going to his back and looking for a submission.
There’s probably no good way to fight Georges St-Pierre, but this might be the best way to do it when everything is factored in.
