Did Jim Harbaugh throw shade at 49ers after firing of coach?

Needless to say, there’s no love lost between Jim Harbaugh and his former team.

The San Francisco 49ers announced on Sunday night that they fired head coach Jim Tomsula after one 5-11 season. Tomsula, of course, took over for Harbaugh after he resigned and bolted for Michigan last year. It wasn’t exactly a clean breakup, either.

Well, following news of Tomsula’s firing, Harbaugh had this to say late on Sunday night:

Do not be deceived. You will reap what you sow.

If you think that it was just a coincidence, consider this. Harbaugh hasn’t tweeted a random quote like that all year. And for the Michigan coach to drop that at 11 p.m. right after the news was released, he had to know what people would treat it as.

The national media put two and two together.

The missing line from this interestingly timed tweet, a quote from Galatians 6:7, is "God cannot be mocked." https://t.co/iCDMB29xGo

Turns out Florida wasn't his last win of the year. https://t.co/2IwD4bz4kd

The best revenge is living well. But watching the franchise that fired you flop is an added bonus. https://t.co/D2BW559HBM

Just a hunch but I don't think this one is about any recruit. https://t.co/3F9siQaCay

But if Harbaugh wasn’t taking an indirect shot at his old team, he picked the oddest possible time to do it.
