Nortman was dreadful last year but was a rookie and as rookies should do he worked on his craft and seems to have really improved.
I didn't think Gano was all that bad last year. He had a few bad kicks and everybody likes to point out that missed XP against the Eagles (which was more of a timing issue), but something has really changed in him and he has been dead on with some of his kicks...most of which seemed to be longer than 50 this preseason.
I would like to see what both of them can do in meaningful games and when the game is on the line. But as of this moment, I would be perfectly fine with having both on the team long into the future.
