I don't think Boyd is in very good form at the moment at club level, but when has he ever let a team down at rep level? imo rep teams should be hard to break in to, and hard to get dropped from. If a player has done the job before, they should be given the first chance to prove themselves and as long as the team overall is still performing ok, a bit of leeway if their form is down for a few games.
I think it's important that rep teams are allowed to build a bit of a combination between players, rather than purely picking the current best players in each position. If you chose every rep team based on current form, it would change each time and not allow those combinations to build up. Even know the current QLD team has some exceptionally individually talented players in it, i think that they have been able to stick with those same players for a number of years now has allowed them to build good combinations in the team, and when the games are on the line, I think it's the combinations as much as the individual players that allows QLD to come through.
