Skip, no one actually plays on the half forward flank anymore. Do you think opposition coaches are going to put a bank flanker type on him simply because he walks over to the flank position at the start of the game. Reilwoldt is always going to be a key target inside 50 for us, especially the long bomb when required as his contesting marking is so good - so by default if nothing else he is going to be a KPF for us, regardless of the inclusion of Griffiths and Polak types. If Glass had played, he would have played on Reiwoldt. For quite some time opposition clubs will be playing their best key backs on him.
And as for double teaming, I can't recall the last "flanker" that was required to be double teamed.
