I think Francis would be replacing Ambrose when he breaks into the best 22, his ability to be effective going forward with Hooker coming back in the case of a gorilla opposition forward cutting loose will help his cause relative to Ambrose.
Also, I think we have a more dynamic backline with Francis in it instead of Ambrose.
But what keeps Ambrose in the side is you know he will compete and nullify effectively and is relatively bombproof from an endurance and physical perspective.
If Francis can get his body right I think it is a no brainer to have the 3 tall defenders as Hurley, Francis and Gleeson - with Hooker to go back if necessary. But if we can get Hurley, Francis , Gleeson, Baguley, Saad, McKenna (with some back up from Goddard) all clicking together, then opposition forward lines will need to be very accountable and gorilla forwards may be more of a liability than an advantage against us, that is if we can transition forward quickly as this backline would let us. With improvement midfield also on the cards, the increase in forward entries could boost our forward line into the best in the league.
Although the reliability of Ambrose is a great back up, as is the size of Hartley if needed to keep Hooker forward - I really think we need the dynamism that Hurley, Francis , Gleeson, Baguley, Saad, McKenna (oh that we could afford the luxury of McGrath over Baguley) - I can really see us tearing teams to shreds if we improve the dynamism in the middle with a fitter Heppell, Zerrett, Smith, McGrath, Zaka and Belly in the middle (with support from Parish, Langford, Begley, Stringer, Walla, Raz and Goddard) which will also largely rotate through our forward line with Joe, Stewart and Hooker being our 3 tall forwards.
We are on the verge of being the most dynamic side in the competition and Francis is potentially the missing link to get our backs fully functional on the counter attack.
All I can say is I hope he can start putting it all together and start to become a senior player ASAP, if he clicks and stays fit there is no stopping us.
