49 is a common number for you? Yeah, obviously for a test match you pick your best 32 from 50 on tour. That's not fair for the opposition.46, 49 & 41 in the last 3 tours. Both include all players called up even if they never got on the plane to start with, whether through injury or other reason (Dylan Hartley and Ben Youngs in '13 & '17 respectively), alongside the "call ups of convenience" for mid week games: of which only 3 actually got on the pitch (70 minutes for Shane Williams v Brumbies, 25 minutes for Tom Court v Rebels, 5 minutes for Finn Russell v Canes).
Obviously depth is a big factor in ability to accommodate a series of injuries (using 6 different looseheads on the 2013 tour) but when it comes to the tests themselves, the BILs used 32 players in 2013, 26 in 2017 and 31 in 2021: those numbers aren't unusual for NH outbound tours.
Never has a Southern Hemisphere team on tour brought 49 players cause none have 49 international players like RFU, WRU, IRFU and SRU playing together. Let's be honest. That's the main strenght of Lions
