The tweet that started it all:
Recall that the Jets have hired Charley Casserly to assist in the process, and then read these tweets from John McClain:
Jets interest in Texans dir of college scouting Mike Maccagnan makes sense. He worked with Casserly in Wash and joined him with Texans.— John McClain (@McClain_on_NFL) December 30, 2014

Mike Maccagnan has been the Texans' Director of College Scouting since 2011. From the team's web site announcing Maccagnan's promotion to that position more than three years ago:
Maccagnan has been with the franchise for 12 years and served as the assistant director of college scouting since June of 2010. In his new role, he will coordinate all of the Texans’ college scouting efforts. In addition, he is involved with evaluating NFL teams and prospects in preparation for NFL free agency.
One of the Texans’ first hires, Maccagnan initially joined the club as a pro scout in January 2000 before being promoted to coordinator of college scouting in April 2000.
Before arriving in Houston, Maccagnan spent the previous six years as a scout for the Washington Redskins. Prior to his tenure with the Redskins, Maccagnan was the director of scouting and player personnel for the CFL’s Ottawa Rough Riders and Saskatchewan Roughriders (1994). He also was the director of player personnel for the World League’s London Monarchs when that franchise captured the league championship in 1991. In 1990, Maccagnan worked in the World League office as a league scout.
