Cardinals owners Bill and Michael Bidwill were part of a team contingent at a private workout for quarterback Blaine Gabbert on the Missouri campus Wednesday, a league source told ESPN NFL Insider Adam Schefter.
Cardinals coach Ken Whisenhunt, general manager Rod Graves and personnel chief Steve Keim also were spotted in attendance at Gabbert's workout, the source said.
According to the source, the team took Gabbert out to dinner on Tuesday night.
Gabbert is ranked as the No. 1 quarterback prospect of ESPN.com's Mel Kiper and Scouts Inc. He threw for 3,186 yards and 16 TDs with nine interceptions last season for Missouri.
All 32 teams sent officials to Gabbert's pro day on the Missouri campus on March 17. Gabbert completed 44-of-49 throws in a scripted sequence laid out in advance by private quarterbacks coach Terry Shea. The script included hitch passes, fades, deep outs, five- and seven-step drops, rollouts to his left side and more -- with a makeshift cast of four small-college, draft eligible receivers whom Gabbert had to rely on thanks to restrictions under the NFL lockout.
The Cardinals have the No. 5 overall selection in April's draft and are searching for a starting quarterback after a disastrous 2010. Arizona won just two of its last 11 games, while starting three different quarterbacks after releasing former first-round pick Matt Leinart before the season.
