One of the more interesting developments coming out of Miami Dolphins training camp has been the emergence of wide receiver Caleb Douglas. That's a small problem for a young receiver, and it's usually fairly easy to correct. The Dolphins have some uncertainty at wide receiver heading into the season, which makes this competition particularly important. It's still early, so nobody needs to start engraving Douglas' name onto a starting lineup just yet. But he's already doing what a young player needs to do in August.
