Yeah, Kentucky fans already referred to him as P-Pat. I think is by far the best. It's simple, doesn't sound gay, and has a good cadence to it when spoken.
I originally though just Pat. But now, Pat-Pat and Project Pat have grown on a brother. If he proves to be a reliable 3 point shooter, I'd like to be on record of calling him PaTHREE first.
The two that originally came to mind were PatPat and 2Pat, but after reading through the thread I'm gonna keep it simple and stick with "Pat" for now. I did however like St. Patrick, but I'd shorten it to St. Pat if I had to sign off of on that one. After the summer league games something might stick out in his play, and from that we can come up with a personalized nickname.
