Confirming @espnsteinline tweet -- league's projected cap/tax for 2013-14 is currently $58.5M & $71.6M. For 2014-15 it's $62.1M & $75.7M.

As the tweets indicate, these numbers aren't final until July but they don't often change much. Basically this means that the cap and tax lines are relatively flat

If this stays true then the Raptors aren't at risk of taxes.
