Benjamin Nochman: respected Den asst coach tim grgurich "unlikely" to return this yr, source said. grg could still be with team in some capacity 

I know that Grg is considered one of the best player developing coaches in the NBA and if he leaves, he will be greatly missed. But if he does stay with the team (though not as an assistant), then it shouldn't change much. The problem I see is, he's the kind of coach you want with young players (like Lawson, JR, Afflalo ) and if there is an impending youth movement, he would've been good to keep.
