The salary cap for 2017 is £1.85m. What part of that don't you understand? Why would 2016 have any relevance to the Wolfpack?
And your "examples" was a list of proper professional sporting competitions that in no way proves this crap about there being 200 players contracted. Every piece of available evidence says otherwise. Apparently a 15-a-side game needs 40 players to play a grand total of 12 games but only lists 30 players or less. Riiiight.
Just found an article that backs you up. So I will concede on that front.
And the NFL often have 100 players on their payroll. They only play 16 games a season. The MLS runs deep squads often farming out players to loeer league teams but they train with the main squad.
