Theres a big difference between a 5'10-180lb 13 yr old and a 5'10-180 15 yr old. Im not trying to scare anyone. My son plays on a elite travel team that always plays up a year or two. And it got a lil scary when we were a U13 team playin at NXT Cup in the U15 B division. You start getting into your third game of the day on a hot summer day and your boys don't have the stamina anymore and cant play at full speed like the older kids. Things can get very ugly. Thank God we escaped without injury but I can see it happening very easily. I always been a firm believer of playing up but as you get older the boys become bigger and faster and play the game at a different level. Lets start putting the kids safety and well being first and teach them the game of LAX in front of winning a tourney. You remember state titles and national championships. Not a medal from winning a tourney at Laxfest. Lets keep it real and do the right thing!!!!
