Squad sizes

Would it be useful to restrict the sizes of squads that teams have? I played someone yesterday who has 331 on his list, many young players who are nowhere near as highly rated as his first 15. Other than the fact that this denies other people the chance to buy them, what is the rationale?
He is training young players now ahead of future seasons ?
So he speculate to accumulate in auction house ?
So he can have multiple teams, so can defend GvG whilst other 15/22 rest ?
Geez Taff your prices for players dont go cheap no chance the rest trying to compete to get anyone
All part of life's rich tapestry
The rich get Richer and the poor Well they suffer
Part of professional rugby management lol

Anyone specific you needed ?
No just trying to compete against you 140 chaps my team all around 100 but when bids go up to 40 k i can not compete
So when i lose 17/14 against you i am proud of my boys
I can only count on Strat
A good game Goldys
