after I was selected for my first U21 run, we started to train guys in SB. this was one of my main points. at the beginning it was hard to convince the managers to train SB rather than IS or rebounding. But now... it works. if i take our 19j old guys, we have already around 10 players with SB 10 or higher. and other guys (around 25) just a little bit behind. so this whole SB conversation is, for us, somehow amusing. i don't say that we will have the best team or win everything. no. but we will be in a good position, because we have already a solid basis against LI teams.
so Manon, you are not alone ;)
