Just checked the T-Wolves roster on hoops hype and I'm guessing that their aim is to keep a low cap figure and have no big contracts on their roster (Beasley is the highest earner at $4.9 mill). Projects to be that way for a while as most of their active players are also under contract for next season as well.
This season their cap is at $45.4 mill and in 2011/2012 it projects to be at 41.7 mill.
The 2012/2013 season may end up being a make-or-break season for them as that's when Love can be a free agent, as well as them having numerous players with team options or a qualifying offer (Beasley, Flynn, Wesley Johnson, Webster, Ellington).
They could potentially have alot of cap space that summer, although as we saw this off-season, cap space doesn't guarantee quality players.
