Bruce of the team that played Saturday 7 were 2nd year players.  Lamont, Hodge, Frazer, Dargaville, Boyd-Jones, Armour, Cannon.  Add Tully (3rd year) and Tolu, who are regulars, and it seems like more than half are secong year players.  Your Colts 2 are the same.  The West Harbour match should be good to watch.  WH are always a tricky side at Concord.  I think the Manly performance vs Uni was very sharpe and Manly will be a handfull later in the year.
Another player who has returned is last years Colts 1 halfback James Helliwell.  He was playing league with the Sydney Roosters U20 side and is still listed on their website as a player.  How come he is playing rugby and will Helliwell be back in Colts this year?
