I agree we shouldn't lose Barba ... i want to see how he performs next season first. he had a bit going on at the start of the year and that affected his performance IMO. New city, new team, new style of play, ankle injury that hadn't fully recovered, his psychological issues that he was trying to deal with, Griffins bulk everyone program ... oh and the biggest one of all is he had Hoffman as the 5/8. all that combined would have made life tough for plenty of quality players, but he was showing some good signs towards the end of the season.
as for ditching Kennedy and giving his money to Boyd, that would be a mistake... we are short in the front row as it is, so if we are losing Kennedy we should be giving his money to a big, tough, young prop. not a winger who wants to play fullback (we already have one of those)
