I'm not sure if stats back it up, but it seems like when Iguodala is not guarding Lebron, Lebron seems to go off more - whether it be on Barnes, Klay, or even Green.
A guy like Iguodala is indispensable, much like Kawhi last year. Kawhi was unreal in 2014. Just feel like he's the MVP for that reason, even without gaudy stats. Kawhi's 20+ point outbursts sure helped his case last year for sure.
