Fulham are going to end this one with something like 65% possession. Obviously they're not good, but more importantly for a team fighting relegation, they're not intimidating at all. Every team in the league is going to be thrilled to see Fulham pop up on the schedule. Contrast that with like...Burnley, or Stoke's run in the league. They need reinforcements with some bite, both in midfield and defense, or they might well go down with the worst goal difference in Premier League history (currently 2007-08 Derby, -69). They're at -7 after three games against teams that finished 8th, 17th, and 1st in the Championship last season. That is a really bleak start to a season.
On the plus side, it wasn't the worst day for Ream, who played, and a pretty good day for Robinson, who didn't.
Yes, something like 23% for top 5 leagues per analysis below done in 2017. 1 goal for every 64 crosses. https://soccerment.com/crossing-effective-strategy/
