I've had to take it from Eppley to my home in Lincoln twice before. it was about $90 at a non-surge time. You could probably expect to at least double that, probably more. Some drivers might not want to take your fare after a game though too.
3 of my friends did it last year for a game. If I remember correctly they paid about $40 a guy. To give you an idea on geography they live around 42nd and Center.
