Basica my point on Estevao, most player gain upper body mass. I've seen multiple ACL's from putting on upper body muscle. Your weight affects your gait, all of our players with long term injuries are stronger young guys with lots of muscle. It's a running sport, you carry extra weight, you fatigue differently and your gait reacts. Colwill, Fofana, James, Guiu, Tosin, Essugo, Sarr and Lavia are our heaviest players. Tosin has the age and height for his weight, Guiu has been clean, Sarr hasn't had any premier league minutes all others have had a share of lower body injury issues.
