Good catch, and an excellent read.
I don't really have a strong sense who's right here: We had zero offense off the bench and no true backup point. From that standpoint, it looks like a no-brainer signing. Plus, I suspect that Steph will make House a better player at the 2, while providing more punch and experience than Pruitt.
Conversely, the author lays out pretty convincingly the downside of this deal. And the only more distasteful person I can think of to wear the green is Kobe.
My take: We weren't going to beat Cleveland or LA, and potentially others, with the bench we had so this is essentially a "hold your nose" deal. If it works well enough to play a significant role in a repeat, then Danny gambled and won. If it doesn't, I don't really know what we lost.
