Look at it this way: Is McLean as good as, or going to be as good as, say, Joel Selwood, Ablett, Bartell, Enright, Corey, Ling, Dal Santo, Hayes, Goddard, Judd, Gibbs, Murphy, Black, Cousins, etc, at al, and the rest of the leading on-ballers in the comp? So far, he's not half as good as any of them, and given his progress since the 2006 final against StKilda, he's not going to get any better, or quicker. If Carlton want to give us pick 11 for Brock, then we should take it while he has (or Carlton think he has) some collateral value.
