OUT OF THE ASHESIf any coach of a 2-3 team ever deserved a new contract, it's Gene Stallings of the Cardinals. Four of Phoenix's five games have been on the road. In a 30-28 loss at Washington on Sunday, the Cards lost Roy Green, their best receiver of the past decade, with a broken collarbone. Before that, 11 starters missed at least one game this season, including Neil Lomax, their best quarterback; Stump Mitchell, their best runner; Lonnie Young, their best defensive back; and Freddie Joe Nunn, their best pass rusher. "Do you know how tough it is to lose so many players and keep people motivated?" says tackle Luis Sharpe. When wideout J.T. Smith caught his third touchdown pass of the season with 14 seconds left on Sunday, he was mobbed by people named Ernie Jones, Don Holmes and Mike Zandofsky. They're all Cardinals. After recovering an onside kick, Phoenix was just shy of field-goal range when time expired. Stallings is in the last year of a four-year contract. Owner Bill Bidwill should reward Stallings with the chance to take a healthier team into the 1990s.
