GRIZZLIES NEW OWNER CHANGES TERMS ON LEASE DEAL

          Incoming Grizzlies Owner Michael Heisley has shortened     the team's lease at GM Place from 15 years to five,     "narrowing his risk in the event that his $160 million US     club doesn't reverse its financial fortunes," according to     Howard Tsumura of the Vancouver PROVINCE.  The NBA has     "indicated" that five years is a "reasonable length of time     for Vancouver to prove its viability as an NBA city"     (Vancouver PROVINCE, 4/14).  Orca Bay President Stan     McCammon confirmed the team's reworked lease but said     "there's nothing to read into it" (VAN. SUN, 4/14).           READY, SET, HUTT? Tsumura adds that sources say Blazers     Senior VP/Marketing Operations Harry Hutt "turned down an     offer" to become Grizzlies President (Van. PROVINCE, 4/14).
