Most likely, it's hiring someone for Isiah to delegate tasks to if he's going to be wearing both a coach's and GM's hat this year. Because all Isiah/Knicks smartassery aside for a second, doing both jobs at the same time is a hard thing to pull off.
He is only there for the money man. Remember Lebron James dunked on him and how Jones was all pissed off last season? He hates to play for the Cavs and loves to stay in Miami if it wasn't for the money. BTW, He is a great shooter but not a good passer.
