Taking a match in his downtime between Summerslam and Wrestlemania like I guessed. Book him vs Dos Santos for October, November or December cards. Guaranteed money.
Cain Velasquez will almost certainly be in line for the next UFC HW title shot at JDS after his destruction of 'Big Foot' Silva last night.
Daniel Cormier is also rumoured to be joining UFC from Strikeforce after winning their HW Grand Prix and Dana White has said he would instantly be in the title mix.
If Lesnar goes back to the UFC he would have to fight at least once, most prob twice to earn a title shot after his last three performances for the company.
The HW division in the UFC is now stacked and as much as i like him i really don't want to see him go back and get destroyed again.
He was the UFC HW Champion when the division was just starting to become stronger (Big Country, Silva, Carwin, JDS, Cain, Overeem, Werdum arrived shortly after him).
Also Lesnar big deficiency in MMA was his striking, JDS would absolutely murder him as he is a world class boxer with amazing take down defense.
Lesnar would most prob face two of either Big Country, Silva, Cormier, Werdum or Carwin / Mir again to earn a title shot and even *If* he was to beat JDS then he is going to have Valasquez and Overeem breathing down his neck (two men who destroyed him).
The moral of the story for me at least, is that Brock should stay in WWE and pick up that easy $5 million for three or four worked big name match ups against Triple H, The Rock and then Undertaker at Mania.
Lesnar made $5.2 million in his highest earning UFC year, not enough to put your long term health or even life on the line when he can make $5 million in the same time frame for four WWE matches.
