Happy enough with that Eng side. Very powerful back 5 of the scrum. I'd always find a place for Watson if his form's anything like; tough on Nowell, but he's a great bench option.
On the other bits earlier in the thread....
I sometimes think when people talk about the NH falling short of the wonderful ball handling SH, they actually mean the ABs. Aus blow hot and cold and have been beaten plenty of times by the NH (well Eng anyway.....and if some of those were solely through the forwards, so what? The scoreboard is sole arbiter, there are no marks for artistic impression and Aus have often played the looser game only out of necessity as their pack was cr*p). Ignoring SA's current woes, they've always been forward oriented. So the question isn't how can the NH catch the SH, its how can the NH and the rest of the SH catch the ABs. And as I said on another thread its maximising your strengths, not trying to mimic theirs.
Re bringing players in, it really shouldn't be difficult via the bench these days. 10 mins here, 20 there. The ABs were the model - the 2015 side was uber experienced, yet there were players with 20 or 30 caps or more waiting to take over. You can experiment through the bench, but a starting shirt should only change hands if someone's made a compelling case that they're better. Although you need to avoid teams getting old together, experience and cohesion counts.
