Hard to say. Nikorima definitely would make an okay Robin next to Reynolds's batman, but I think we currently do have the players we need to make the eight. It would just require some re arranging.
For some reason the club have had the right centre as a more offensive option and the left as a more defensive. It's a throwback to Hodges and Reed, with Bird and Roberts being in the same boat.
But if they were to tweak it and move Staggs to the left and Farnworth right, Herbie gets the ball more off Reynolds, and Staggs offensively can make up for our options at 6, allowing them to just tackle, run in support and occasionally kick like they currently do.
