Have a look at what the Broncos did to Prince at the back end of last season. He played some of the best footy of his career.
They can do the same with Marshall. Perhaps reign him in a bit and play a more structured and disciplined game. But they could certainly use his play making ability as in, passing the ball when necessary and to a point, his kicking game.
The new strength and fitness coaching staff at the Broncos would basically break him and then rebuild him as it seems they've done to the rest of the team with outstanding results.
