I think he can be an effective starter, yes. I make the backup comment because I'm asking myself not whether he can be merely effective but can he lead a championship caliber team. Maybe that's not fair or relevant, but hopefully clarifies.
Yes, I was high on Rivers.. and I'm still curious, tbh. I was high on Selby because of his major slippage. Like Kabongo.. one person asks me if I like him when he was mocked at #7 and I said no. Another person asks when he's in the 2nd round and I said yes.
And yes.. none of us get them all right... I feel like I've been right way more than wrong, but still wrong too often to ever be taken too seriously.
