They are both awesome players. Samuelson has unlimited offensive talent and potential, but she needs to improve her strength, athleticism, and conditioning to reach her full potential as a player. She has not hit her ceiling as a player, or close. Collier is better physically and athletically and never has any bad games. She is one of the most consistent UConn women's players I have ever seen. Her post moves are polished and double teams and physical D and bigger defenders do not bother her. She can also shoot the 3.
