Barnes have back spasm...in my opinion that will affect his speed...maybe its just me, whenever my back hurts, it affects my speed and strength in terms of working out, playing basketball or volleyball
your back is very important...therefore, if he does cover ray, ray will outrun him...i expect Ray to take advantage of this if this is true...
VC on Pierce on the other hand is a wildcard...Pierce can probably use his strength on VC, but im afraid of VC going off offensively
