Check out five opinions trending online, from the Tommy John epidemic in baseball to a comma queen.
Hillary in the gray zone: The Washington Post editorial board takes issue with Hillary Clinton's contention that she used personal e-mail to do State Department business because she only wanted to carry one device.
"In the end, it is clear Ms. Clinton was acting in a gray zone, one created in part by the rapid pace of technological change. But it is also apparent that her decisions on her e-mail were based on what was best for her — what was 'convenient' — and not so much for the public trust." Read more.
Behind the Tommy John epidemic: Baseball spring training is in full swing, and as part of Grantland's 2015 MLB Preview, writer Jonah Keri breaks down all the pitchers who are, well, breaking down.

"Now here's the scariest part: While Tommy John surgery has a high success rate, 20 percent of pitchers never make it back to their previous level of performance." Read more.
Shut it down: Although the University of Oklahoma took the right disciplinary measures after a racist Sigma Alpha Epsilon video surfaced, writer Lindy West contends in a column for the UK Guardian that the entire system is toxic and should be shut down.
"The racist chant that Oklahoma's SAE brothers shared behind closed doors is a perfect distillation of everything that's wrong with this system," West writes.

The law, pure and simple: Harvard Law professor Cass Sunstein finds a decided lack of polarization in two unanimous US Supreme Court decisions this week. That, he writes in Bloomberg View, is reason for optimism that the justices are able to focus on the law, not politics.
"Is law just a form of politics? Is the Supreme Court highly politicized? If you focus on the court's anticipated divisions over Obamacare and same-sex marriage, you probably think so. But the court's two dissent-free decisions Monday offer a different picture. They are a triumph for the ideal of a Supreme Court that focuses on law." Read more.
