pointless comparing players with the likes of Rooney, Rooney was a freak at 16, basically fully grown then and already physically strong. 99.999% of other players aren't in that position, and it isn't hard to imagine how someone of Colwills build might pick up some niggling injuries after growing an inch or two.
I seem to remember Steven Gerrard having a late growth spurt that he struggled with for a season or so before bursting onto the scene when it had all settled down.

By the 1999-00 season, Gerrard was making more appearances and slowly building up his presence. However, he was plagued by back and groin injuries, the latter requiring four different operations despite his young age. Most of his back pains, meanwhile, were attributed to accelerated growth over a short amount of time.
