Keep your fingers crossed, Dallas fans ... according to Jimmy Johnson, the Cowboys could very well end up getting Odell Beckham Jr.!
TMZ Sports got the former Dallas head coach out in NYC on Tuesday ... just two days after the Cowboys blew a big lead to the Green Bay Packers and fell to 6-3 on the season.
Johnson made it clear to us, he thinks Big D could use another wideout in its offense to prevent a similar loss from happening again .
