If it's a 4yr/$63M deal I believe his first year salary would be $14.15M and MIN would need to send out at least $11.3M in salaries.
Assuming they wouldn't trade Pekovic and PHO wouldn't want Martin, MIN would need to get to $11M thusly:
Barea = $4.5M, 1 yr
Turiaf = $1.5M, 1yr
C. Brewer or Budinger = $4.9 or $5M, 2yr
That gets MIN to right at $11M so they'd have to either (a) swap out Shabazz Muhammad for Turiaf or (b) S&T Robbie Hummel at ~$1.1M and include a pick.
Not sure why PHO would do this unless MIN includes a #1 -- unless they want to have $15M in expiring contracts (Barea, Turiaf, Green, The Morris Twins, Shav Randolph) to use in getting a big time player in a trade.
