Unless they are going after the highest profile guys, fans don't really care. Putting out a press release saying you signed a 16 year old noone has never heard of does matter to most people.
I'm not saying they need to state who they are going after or even where. But it isn't asking a lot to mention that they are interested in "several players" and then do like Linty said, put out a little background on each of the players.
