What are you guys doing with the fact Esposito never was a + player (and was close to being such only once) as a Ranger?
I would say the Rangers were a mediocre to bad team.
'76 - 10th in goals for, 16th in goals against (out of 18).
'77 - 7th in goals for, 17th in goals against (out of 18)
'78 was their best season of these - 6th in goals for, 11th of goals against (total differential -1, but they look more PP dependent of the league as a whole, scoring 78 PP goals against a league average of 54).
'79 - 4th in GF, 13th in GA (again very PP dependent)
'80 - 6th in goals for, 11th in GA (lots of PP here, but considering Espo was kind of declining his numbers might just be a better reflection)
'81 - 12th GF, 12th GA (-5, actually less PP reliant this time but considering Espo is done as a player probably plays into that).
They not shockingly had a bit of a drop off from 75 to 76 defensively, going from 11th to 16th and allowing almost 60 more goals.
But again, Espo was never a great defensive player and I don't think anyone is suggesting he is.
