Zach Johnson calls out Jim Harbaugh, is taking National Signing Day very seriously

National Signing Day is Wednesday, and judging by what Zach Johnson tweeted on Monday, he's extremely invested in the proceedings regarding his Iowa Hawkeyes. Upset that the University of Michigan made a last minute offer to an Iowa recruit, the two-time major champ took to Twitter to express his displeasure. The tweet has since been taken down, but Bleacher Report got a screenshot of it:

By "Khakis," Johnson is referring to Michigan head coach Jim Harbaugh. The Wolverines are one of the Hawkeyes' biggest rivals, and all Big Ten football teams have found recruiting top talent a lot tougher since Michigan hired the fiery coach after the 2014 season. Harbaugh went 10-3 in his first season in Ann Arbor and things only look to get better. currently has the Wolverines' current class ranked No. 7 (Ohio State is No. 1), and that could change if they sign top recruit Rashan Gary.

Iowa is coming off an 11-2 season (Johnson served as an honorary captain for one of the games) and a trip to the Rose Bowl, but is only No. 41 in's recruiting ranking. On the bright side, for Johnson, the recruit in question -- three-star offensive lineman Alaric Jackson -- officially committed to the Hawkeyes. Hang in there, Zach, it's going to be a long, stressful day.
