I think younger teams playing in older divisions helps with the development of the players and teams - as long as they are competitive (nobody wants them to lose interest), as these two team appear to have been. The true test of this is when they play against teams comprised of their true age-group. However, my sense is the physical develepment bubble season for the boys is in the 13 year old spring season - kids get bigger and stonger. In addition to competitiveness, safety should be a consideration when the boys are playing against young men. This decision should include the player, parents, and coaches - but there's no arguing the physical differences between players that will be evident this season. The U-13 league is competitive, and has some great players and teams. And may I add there is little of the bad blood between teams that I've seen in other age groups? Here's to a great season. Good Luck to all and Cheers.
