I'll wait until the England team is announced tomorrow. Fascinating games ahead - I have this feeling that the Sweaties might come good against the French after some near-misses in tough games, and the Welsh (generally thought to be the form team) beat Ireland only after a dodgy penalty decision, and only put daylight between themselves and Scotland after the latter had a rush of blood resulting in two bins.
At present, my tentative view is:
Ireland by 15
Scotland by 7
Depends whether Farrell and Hodgson play; if so, Wales by a reasonable margin; if the back line is adjusted to include Tuilagi and Flood, then England may just hold the Welsh off: though no-one will be claiming the English outplayed the Welsh come what may.
