Gladman..if it is really only 2 players that were on the Under 17s that not on the current Under 20s..then that is remarkable. One should expect the team to change far more than that.
I have little knowledge of the situation, but if a player chooses to play for his school..while others chose to play with the Under 20s, it is highly likely he would get dropped..at least in the short term..and not because of retribution or bad mind, but because the coach may have found one or two players for his position who he works with daily and who the coach trusts. The new player or players will know the system and may have better chemistry than Molino.
I really doh know. Not saying that is necessarily the case, but maybe something to keep in mind before we start the conspiracy theories
