In my view Smith should be the starting 7 for most if not all games. OK if Lam wants TL to start in games v Wire, Saints & Leeds then ok, as for the rest Harry Smith should start. TL should be the bench player not Smith.
We already have Hastings and Lam has brought Field in.
The season starts with us having one wingman, Manfredi, and not doubt he'll start on the right side.
Field should start on the wing in the absence of Marshall. OK he's not played there before but playing there at training will give him some idea what's he will be up against. There is also the option to move him to the middle for the last 20/25 mins when the opposition pack and halves are tiring. Doing that at the back end of a game could prove devastating with Field's pace.
This is the overall problem we now have with no centre or wingman cover but a surplus of halves and forwards.
