I don't think it's binary: great or horrible. Kincaid is looking like a hit, Coleman is trending to be a miss. Samuel is a miss. Palmer may be decent, but probably no better than an average number 2 at best.
Beane's done ok, not great, not horribly at getting Josh weapons. The problem is OK probably isn't good enough to win a Super Bowl. And Josh turns 30 next spring so time is running out.
