Sweatt has unbelievable speed, but what sets him apart is his ability to make plays at high speeds. He also has great acceleration. Sweatt possesses great hands and is smart in his decisions with the puck. Rarely can he be found turning the puck over. Sweatt's superb defensive play and awareness is one area that has progressed quite nicely this season, and has made him an effective penalty killer. Sweatt also possesses excellent on-ice vision and has a keen sense of being able to find open spaces and knowing where the play is going to end up. While Sweatt has all of the necessary tools for future success, adding size and strength to his 6'0" frame will be essential to his pursuit of achieving that success.

Colorado College head coach Scott Owens' comments on Sweatt: "We've been very impressed with Billy's overall performance. His overall speed and ability to open things up were such that they were obvious from day one. Sometimes Billy goes so fast that it's hard for guys to stay up with him. He has a very good team game concept and we feel confident with him in all areas. He's been really good for us."
