Very possible.
But whether they would play "better" or "worse", I assumed they expected an improvement in their points tally.
As I said in #1385, Hull's points per game was unchanged after Silva took over (30.0% versus 29.6%).
Compare that with:
Paul Clement - 29 points from 57 = 50.9%, versus 12 from 57 before him = 21.1%
Sam Allardyce - 28 from 66 = 42.4%, vs 13 from 48 before him = 27.1%
Craig Shakespeare - 23 from 39 = 59.0%, vs 21 from 75 before him = 28.0%
As I said, I'm sure Hull fans have their reasons which are unknown to an outsider like me, but I just think it curious that Silva is so "lionised" as a manager despite, not because of, what he achieved at Hull.
