And to a lesser extent, Douglas and Walker.
Regardless of rotation or coach we are gonna need guys like this down the road. You gotta have some injury cover it's rare that teams go all the way through the playoffs without at least a few small knocks and missed games.
Fields is a solid all round player he's successfully defended Kobe Bryant and put up good numbers this year. I still think he should be our starting 2 with Smith off the bench as we need scoring in our 2nd unit. He can grab a few minutes behind Melo/Novak too there should be enough minutes to go around for Smith, Fields and Shumpert if we play them situationally and adjust depending on who is performing on any given night.
Douglas and Walker can play garbage time all season for all I care. But they both have the potential to go off if the stars align, both can light it up from 3 and both can defend well., the key attributes of a bench threat. They could come in really useful during a deep playoff run.
Unless we can trade them for a pick (doubtful) or a serviceable PG (doubtful) there's really no need to trade them. At least they have chemistry with our guys which can be important.
