It's interesting reading this.
As I currently have
Salah, Sterling, Kane, plus Van Dijk and Martial.
Also in there are Ceballos, Ederson, Maguire and King, so I'd hardly say it's the big hitters and a team of chumps!
There's 2 x 4m defenders, but as one of them got a 14 pointer last week, and the other got 6 on the opening day, they're hardly dead weight.
The only dead weight player in the team is Greenwood, but 3-5-2, or 4-4-2 has worked well so far.
The thing you're ignoring by focusing on a "points to cost" ratio, is that they might not be good captaincy options.
That's where the big hitters, that you're leaving out come in.
