its clearly francophone factor.
1) desharnais was mainly a C during his time, so he'd be the 5th centre.
2) the fifth centre is the only position that has a fifth and weirdly, its Tatar, who was a Left Wing,,, and that line would be the Tatar - Danault - Gallagher a line for years.
I'd also put Ryder ahead of Desharnais.
