What, you mean like scoring forwards who can handle and create their own shot, and have JS/JR to rival a shooting guard but can also score inside if their man overplays the outside shot...oh wait, that worked well for me--McNeill and Faina quite obviously gave your team fits (6-17 and 8-18 shooting respectively). Good rebounders might hurt you though, and I definitely lacked those (my starting lineup had no one above 7 rebounding). Or are you talking offensively, your offensive flaws might get exposed against better (outside) defense?
And as far as revenue and training go, at least you can probably lose this next game, and if you can't I guess there are worse problems to have than being so good that you can't lose an away game in the Finals even if you want to and play all your backups at low enthusiasm.
