Im sure they measure all the players in shoes. Most high end basketball shoes especially for a D1 athlete at UK are going to have a inch or inch and a half support and cushion.
The weight is probably topped out after they have been through numerous strength sessions throughout the summer to maximize the look of the roster. I.E. they will not list say Braydon Hawthorne coming in at 177lbs UK will wait untill after they feed him 5k calories a day the whole summer and workout with him daily and then list him at his maximum weight before the season tips. BH comes in at UK 177lbs maxs at lets say 198lbs drops before the season starts to 191lbs so he will be listed at 6'9" 200lbs round up the most he weighted 198 to 200.
