in that situation with the new starting line-up, she's probably considered a forward. Erika, Britt and Yvonne are the guards. whether she actually played the forward is probably open to interpretation. she definitely crashes the boards and rebounds like a forward. but she also shoots the 3 extremely well, like a guard/small forward.
Kat has played SF/PF/W and has been listed as G. Very versatile player. I believe,with the lineup the last two games, she and Kristen were playing the post positions, so, yep, she played inside or PF.
