Lin's better. They might be able to play a dynamic two point guard line up at times with Lin moving over to the two.
I think he'll help. If Lin's healthy all season, they may be able to get into the thirties.
No way in hell is a team whose best player is Jeremy Lin getting 30 wins.
In games where Jeremy Lin played last year, the Nets were 13-23, which comes out to a rate of 29.6 per 82.
In games where he didn't play, the Nets were 7-39 for a rate of 12.5 per 82.
That said, I agree thirty is a stretch. I do predict they'll be improved , thougb.
