I think they have to get rid of themselves.
Barrett should take a long hard look at where he sees his future if he does not play many games this year.
Does he want to end up being a crippled old man?
That's what will happen if he continually gets injured.
Yes it would be for the good of the club also to get some salary cap $$$ back, but it may also be in the best interests of both guys long term health.
In saying that I want them both on the park, and I think they are both game winners and would have them in my team any day of the week if fully fit.
