Well,
Of course Neal is not ideal to defend PGs, but he will defend backup PGs mostly. And it's not like Neal will play a lot of minutes as a backup PG. I expect 10 to 15 min at most.
When Parker got injured, Hill did fine as a backup because Manu was the playing the point most of the time. There wasn't a disaster.
If Parker happens to be injured again, the same thing will happen.
And Neal receiving PG minutes won't stop the Spurs to sign a backup PG. Even with Hill, Parker, Manu and Neal, we signed Quinn. I just hope that this time we sign a better cheap backup PG, like Watson as you said.
OKC has 5 PGs. I don't think they will keep Royal Ivey. He would be my favorite to be our cheap backup PG.
I'm happy because it will give Anderson more minutes.
