Fleet Footwork provides great jungle sustain as you clear as well as a burst of Movement Speed for kiting in duels/invades.
Triumph's massive heal is great when paired with natural bruiser-ness of Graves so you can keep fighting and pump out damage.
The extra little bit of Attack Speed on graves is nice for a faster jungle clear and being able to reload slightly faster.
Coup De Grace's execution damage is great for looking to explode enemy squishy champions on ganks.
Absolute Focus grants you a ton of additional AD for a quick jungle clear. You should be able to easily stay healthy enough to keep this active with Fleet Footwork.
