There have been a lot of mock drafts recently, but I'm linking this one because it goes through the supplemental round in addition to the first round proper (separate link), so it gives an idea of who might be available for the Pirates in the second. If things shake out this way, guys like Alex Dickerson, Derek Fisher, Ricky Oropesa, and Josh Osich will all be available in round two. And there's a ton of talent beyond that for rounds three, four, and later. I'd probably go for Osich if this is how it plays out; he'd be a great value at #61.
