That 2017 cap number is going to make me a little nervous during the offseason after the 2016 season. He might get cut or traded at that point. I hate "final year balloons" in contracts.
That number will never come into play; by then he will have all of his guaranteed money.
He can be traded, released, or renegotiated.
In fact by the time that number even come sup, Kam himself will want to renegotiate it to a lower number in order to get more guaranteed money and/or years.
That number is 0 concern.
