looking at the clip of them training it looks like the first 15 will be strong but we will probably weaker from the bench, the standout names that I couldn't see on the clip would be starters are Brookes and Shields. if that's the case we will still have a strong team.
JTA and T Willis I think were both seen in the video. That's a couple of strong reinforcements into the starting XV I'd imagine.
I'm taking other people's word for it on some of these as apart from those that were more prominent, I struggled to spot the rest. But we should be able to start with this lot:
15 Minozzi
14 Kibirige
13 JDJ/MLB
12 Gopperth
11 Bassett
10 Umaga
9 Robson
1 McIntyre
2 Taylor
3 JTA
4 Launch
5 Rowlands
6 J Willis
7 Young
8 T Willis
That's a very strong starting team. Bench will be interesting, especially among the forwards, and front row in particular. If only 4 are gone from the Bristol game, and 2 of those accounted for above, that's only another 2 unavailable for the bench.
