Great defenders can do that to most players. People are focusing too much on the playoff series where BI was asked to carry the (Zion-less) load (what was CJ's excuse for not being defended in an elite way? He was arguably far worse than Ingram). If a team chooses to shut down BI in a future playoff series (assuming he's on our team), then that'll just open up things for Zion, Murray, Trey etc. Too many weapons and you can't stop everyone.
