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:

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.

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