Non-Irish-Eligible/Qualified quotas for the Irish provinces

Just to compare,
Leinster will be getting two world class players, but both are surplus to requirement, and may not start for big games.
However, injuries are inevitable, and having quality impact off the bench could be a difference-maker.
Also both signings are reportedly only for next season, and appearances are going to be managed, Barrett only joining for 6 months, Snyman won’t start ahead of McCarthy in big games.
The tight-head prop situation is interesting, there is a gap being left by Ala’alatoa, but after two years he should be being replaced by a Leinster-produced player. Clarkson is the obvious replacement, and then the question is how to fill the gap behind Clarkson. One way would be to consider promoting McGuire from the academy a year early, and/or use Healy and McCarthy to cover both sides. With Porter, Milne and Boyle covering loose-head prop there should be plenty of cover for both positions.

So if Leinster just stick to two World-Class signings, one forward and one back, that might be a good template for each season, though getting players on 1-season contracts may be difficult.

Munster are retaining Kleyn, and Nankivell has one more year on his contract, and Abrahams is joining on a 2-year contract.
Retaining Kleyn was vitally important as Edogbo is out for at least half of next season, and Snyman is leaving.
Nankivell is turning into an integral part of the centre-partnership, Frisch is leaving and being replaced by O’Brien, with Scannell out on a long-term ankle injury now.
Abrahams is joining as a back three just as Zebo is retiring, and Nash has been given an upgraded and extended contract so would expect him to be in Irish squads next season.

So, Munster will have one forward, and two backs, none would be classed as world-class, and Nankivell’s contract will be up at the end of next season, leaving only one forward and one back the following season (Kleyn and Abrahams have both signed 2-year contracts) so Munster will have to produce a homegrown centre after that to add to Scannell, O’Brien, and Tom Farrell, or scout an IQ option.

Ulster are losing Kitshoff, and will be releasing Ewers in the back row and signing Kok as a winger.
Reportedly there has to be a tightening of the finances next season so Ewers isn’t being retained nor are they seeking to add another forward. The good news is there are a few high quality young players coming through in the forwards. There still might be a case for scouting an IQ forward for next season.

Connacht have 1 marquee player in Cordero, but didn’t really get any advantage out of him with missing most of the season through injury.
Porch is a good squad option, and Hurley-Langton reminds me of CJ Stander, has big performances regularly, only a pity he would have to stay playing in Ireland for 5 seasons to become IQ.

So Connacht have one forward, and two backs, and Cordero is the highest profile but wouldn’t be as good as years ago. After next season they may be down to one forward and one back.

That seems to be the future planned model for all provinces after next season. All winding down from 3 down towards 2, and probably will be looking for higher quality NIE/NIQ signings once it gets down to that level.

I think the end game may be 1 high quality forward and 1 high quality back, with assurance that a high potential player is not being blocked, and possibly no foreign signings will be allowed in the front row or in the half-backs in particular unless IQ.
