Wilson was a highly touted baseball prospect out of high school, and was drafted by the Orioles despite the fact that he was planning on attending North Carolina State.
Later, he was drafted in the 4th round of the 2010 draft by the Rockies, who still had his rights until recently.
The Rockies left him unprotected in the Rule 5 draft, and the Rangers decided that they're willing to take a flyer on him, in the unlikely event that he ever decides that a career change is in order and he'd like to try baseball again.
Rangers assistant GM A.J. Preller discussed the Rangers' reasoning behind taking Wilson:
Preller makes a solid point. Even if Wilson never takes the field a single time for the Rangers or their farm system, it could still be a solid PR move and a decent clubhouse move, if they can get him to speak to some of their young players.
Wilson has always had a great attitude, particularly when it comes to overcoming his height to become an NFL QB, and he's an extremely well-spoken athlete. If there's anyone who could come in and have a positive impact on a team, it's Russell Wilson.
But will he ever even make an appearance in a Rangers clubhouse? I guess we'll see.
