I am wondering whether I should use subjunctive mood in the dependent clause in the following example. Is there a rule for sentences like this? Or they just have different meanings?
There is a team that lost the championship. I think they should have hired me as a coach. Which one of the below sentences should I say?
1 (without subjunctive mood, just simple past, "could win")
"The team should have hired me as the coach so that they could win the championship."
2 (with subjunctive mood, "could have won")
"The team should have hired me as the coach so that they could have won the championship."
