1) Playing with 3 defenders on him? Pretty normal, you'd back him to kick 4-5 on a normal night.
2) Playing with your best defender on him? With no-one to block his space? That's pretty scary. Fev's combination of strength and speed is unmatched by most no.1 defenders.
3) Your 2nd best defender on him? Good Luck. Expect your man to be demoralized as Fev takes marks like it's a man against a kid.
Scenario (3) is what is going to happen now that he's at Brisbane. We have created a monster. With Brown taking the no.1 defender each week...
The Fev would start sulking when Brownie gets the kicks, and next thing, he'll be sitting on the bench with his shoes off.
