So I probably spent way too much time on this, but I wanted to evaluate whether if NYCFC uses 6-8 Internationals as this author alleges how uncommon that would be in MLS. My conclusion is that not only is not uncommon, it is the norm in MLS to have that amount of Internationals.
I made the following chart for your reference
Contained in that chart are the last lineups trotted out by each MLS team. I used their last lineup and included substitutes, since the author was concerned about minutes. I also did not count Canadian DPs against Canadian clubs but did against US clubs (as the author was upset about the notion of Americans not getting playing time). Every International is italicized; DPs are bolded. If you can't read it, here are the team by numbers of internationals used:
Galaxy: 7
Rapids: 4
Sounders: 6
Quakes: 5
DC: 2
RSL: 4
Montreal: 7
Fire: 6
Crew: 5
Revs: 3
Timbers: 12 (!)
SKC: 7
Toronto: 5
FC Dallas: 9
Chivas: 7
Vancouver: 10
Houston: 6
Union: 7
Red Bulls: 8
That averages out to 5.89 but I think the outliers may skew the picture.
Teams that played less than 5: 4
Teams that played 5: 3
Teams that played 6: 3
Teams that played 7: 5
That's that played 8: 1
That's that players More than 8: 3
So 7 teams played less than the 6 Internationals NYCFC are looking at at minimum. 9 teams (almost half the league) are in the 6-8 range.
Most importantly at least 12 teams are already playing more than 6 DPs. That's over half the league.
It's worth noting that one of those low numbers RSL, has two international DPs out which would have put them at 6 more likely. It's also worth commenting that Sporting KC, which the author celebrates as an example of virtuous American players, has 7, which is probably where NYCFC is going to fall in.
So bottom line is this: chill out and enjoy the show. MLS teams haven't gotten their academies up yet to the point where they don't need internationals, so there are plenty in the game today. NYCFC can't be blamed for bringing in players from overseas when their Academy hasn't even been built. NYCFC isn't going to represent a new wave of crowding out American players.
