I like Theis, but really? Of course Timelord.
What I will say though is that at least Theis seems to be available often. Can't really say the same about Timelord, whether it's injuries, or COVID, etc. But Timelord's young and his ceiling is still a lot higher.
Just like Nesmith, I think he'd benefit from more playing time in the long run. You can't really grow and develop + learn from mistakes just sitting on the bench or registering DNPs.
