I gave them both a C.
Nate is an improvement over Eddie House who I think is close to the end of the line. I love Nate's energy, both on offense and defense. But I don't think he's a point guard, and that's what he's being asked to play on the second unit. He's a scorer, and that should be his role coming off the bench, but trying to play point guard is holding him back.
I think Finley is close to the end of the line, also, and that's why San Antonio phased him out of their rotation. He was really pumped up when he got here, and played great for a few games, but he's not going to maintain it.
Plus, he is taking TA's minutes, and we need TA's defensive energy more than we need Finley's experience. Experience is one thing we already had our fair share of.
