Been trying to figure out how bad Sean is as a commentator. Lucky, Clutch Fans was there for me. It seems like the main problem they have with him is that he doesn't give Harden enough credit when they play. I don't personally see that as a problem. I think he talked plenty about Harden, but the biggest reason why Houston was carving the Spurs up was their own poor D, and Elliott harped on that.
Why exactly does Sean have such a bad reputation? I think he is biased, but he is usually tongue-in-cheek when he sees the Spurs get away with something rather than blatantly in denial that it happened. Like I watched the Warriors game last night, and the commentators watched a video where Klay clearly reached over and slapped an Atlanta player in the face, then they responded with, "All I see if that guy go down without being touched". I feel like Sean would have said, "Well we don't need to see that replay again," or "Yeah, he got with that hand there."
There are definitely more neutral teams out there, but Sean seems like a good balance between being an unabashed Spurs fan and a guy who is good at articulating what he sees (and illustrating it).
