4 down, 5 to go
David Neal, guesting for the vacationing Armando Salguero, coming to you live from today's OTA. How do they look? Like a bunch of big, fast athletes running around in shorts and missing their hip flags. It's an OTA day. Practice is closed to the public so the only living thing in the bleachers is a toad. In other news, the Dolphins have signed seventh-round pick, wide receiver Rishard Matthews. He's here along with most of the 2012 draft class. Stanford right tackle-to-be Jonathan Martin and Oregon linebacker Josh Kaddu aren't here. But Martin agreed to terms Tuesday afternoon.
