They are a favourite of mine too! I've been lucky to open a couple of boxes of Origins. Such nice cards in hand.
I started collecting TRoss when PG was getting a little too expensive and I wanted to pick up a nice RPA. I have some pretty strict criteria when selecting a Side PC player and TRoss ticked all the boxes.
1. He dunks the ball and has been in the dunk contest.
2. He can shoot the 3.
3. He isn't too expensive.
4. He plays for the Magic (as they're my team).
An interesting fact about TRoss is that he has scored more points in a single game than what PG has.
