It's all because he's over the hamstring issues. That was the killer with him last year and the year before. That's what was affecting his lateral quicks and that's why people were shitting on his defense. I thought the criticisms were a touch unfair at the time, but whatever, i'm just glad he is over his problems.
Yes he has been great this year. Kudos to Jose. The starting PG slot has been the least of our concerns this season.
