There are plenty informed people in both leagues, but like I said, no one wants to tie up a spot until the "middle of May" as reported by Yahoo. We only have one DL spot, and almost everyone already has someone on it. Plus you have to drop someone first to get him, and most people don't want to lose a player to get an uncertain player who won't play for a month or more.
Combine that with the the fact that, he hasn't pitched in two years, and even then he was great in whip, but nothing special in era, and nothing special in strikeouts his last two years.
Combine that with the uncertainty of how anyone will pitch coming off of surgery, and the time it takes to get back into some sort of groove.
In many informed leagues, he will stay a free agent while roster space is devoted to people who will come back in days or a couple of weeks, not over a month. I'm sure other people will watch his progress like I am, and they'll try to pick him up shortly before he comes back, like I am. It's easy to forget he's in the free agent pool, with no stats from last year or this one, and sitting on the DL. I just plan to be quicker than them.
