Surely the advantage is regular first team rugby? Yes their chances of winning silverware will be reduced, but how much actual credit can a lot of these guys take for winning trophies when they barely contribute on the pitch?
I've seen some Ulster fans cite the absence of internationals, but that is only really Best, Henderson and Stockdale these days so I'd say the bigger problem is that the squad is primarily made up of average players - many of whom probably wouldn't get near to the Leinster or Munster match day 23s.
Even the first choice XV doesn't look particularly strong right now.
I can't see any way for Jackson or Olding to return, so obviously a 10 is a priority, but I'd be less hung up on them being Irish qualified given that this massively reduces the options. There is still hope that McPhillips can step up, so I'd be looking for an experienced 10 who can be first choice for the foreseeable future as well as another reserve who is better than Nelson/Herron. Clearly good 10s in that category aren't exactly readily available, but with Piutau going and Jackson and Olding highly likely to be, surely there is money to spend. After his injuries someone like Pat Lambie might fancy a change of scenery? Robert Du Preez is having a good season so far for the Sharks but isn't obviously in the running for the Boks. As more realistic targets, James Marshall at London Irish is an underrated player who will probably want out after their almost certain relegation and bringing Steenson back to NI as a stop gap would be a decent solution.
The whole tight five needs looking at IMO. When everyone is available, Best, Henderson and Treadwell are decent options at 2, 4 and 5 but that's not very often. I think McBurney needs to be fast tracked at hooker and I know O'Toole is highly-rated so there may be long-term solutions already at the club, but better props and another quality lock are much needed. If I had the choice, I'd let all of Ah You, van der Merwe, Warwick and Kane go and start again. Logovi Mulipola is leaving Leicester and would be well worth a look (I'd say he's better than Moore). Matt Mullan is also rumoured to be leaving Wasps. He's unlikely to get any more England caps with the likes of Genge, Hepburn, Obano etc. coming through, so would be a good choice as a test-standard loosehead. Lock-wise, who knows?
Fullback is also a problem with Payne as good as having retired. I wonder if Addison has been earmarked to play there?
