The TNT crew explaind it best when debating Clutch Shot Rob's foul on David West during game7.
You dont know your injured until the other team starts notice'ing re-marking how a hurt ear flap, would be slapped away at when the other team notices even though you would never be hit on the ear on a regular basis.
Its common practice to go after an injurie but The only thing that worrys me, is Kevin Garnett's relationship with Billups as they are more than just regular friends. That might have an impact on how they treat Billups, hopefully it wont because im 100% sure sheed would hack away at KG if he knew there was an injurie to exploit.
Where i want the team to strike at Billups, is when he's going to the basket, he can kill us when he goes to the line, if he has to go to it, he has to go there after a hard spill on the floor to up the likely hood of a missed FTA.
