This is part of the reason why even for guys like Nesmith, I hold out some hope. Making the transition into the NBA is not an easy one and can take some time. Yes, not every player will work out, but a handful do. Guys like Grant who work hard and ignore the noise can improve greatly and find a real role on a team. I mean just a year ago I remember the entire fanbase was trashing G-Will and saying they should just cut him ASAP lol.
Even Pritchard who had a solid rookie season, but then struggled a bit early this season got a lot of hate, but he's improved and found a more consistent role and groove on the team.
I also don't think you can undervalue how critical Horford has been on this team. I'm sure the guys look up to him and our frontcourt guys also benefit from his demeanor and advice.
