hahaha...I played hockey AND lacrosse because everyone was so small compared to the football players (which I didn't have a problem with either) but you check an ice hockey player (average size 5'7-6'0 170-190) and it's just soooo simple and painless....whereas you pull and slam into a 3 technique (average size 6'0-6'4 250-330) in football and you feel it for a while.....seperated my shoulder doing that, my teammate in practice was 6'5 330 and I slammed into him and was stopped cold.
