Does Adrian Peterson have a good legal case against the NFL?

I attempt to answer this question in a new Sports Illustrated column. Here's an excerpt:

In order to obtain a temporary restraining order, Peterson would need to convince a judge that unless he is allowed to play again this season, he would suffer irreparable harm. Peterson arguing that his NFL suspension will cost him money in lost salary would not be a winning argument for purposes of irreparable harm. Courts are generally skeptical of irreparable harm arguments when monetary damages can later repair the harm. As a result, Peterson would need to establish harm beyond merely lost salary. He would likely insist that not playing again this season would cause lasting and permanent damage to his NFL career and image. More specifically, he might insist that his football skills and physical abilities would atrophy if he doesn’t play again. Similarly, Peterson might assert that the Vikings and other teams would be less interested in his services if he misses nearly an entire season. 

The NFL would reject these so-called "harms" as speculative at best. The league would also stress that Peterson’s predicament is a result of his own misconduct as a parent.
