2 signed, 7 to go

Coming to you live from South Beach, pulling my daughter in a wagon to Flamingo Park pool, this is David Neal, guest blogging for vacationing Armando. The Dolphins have signed defensive tackle Kheeston Randall, a seventh-round pick, to a four-year deal. After not participating in the signing blizzard, the Dolphins have signed Randall and sixth-round wide receiver B.J. Cunningham this week. The only certainty is Oregon's Josh Kaddu won't be the next one -- the school's on the quarters system and, by NFL rule, he can't even take a physical before June 16. I heard the third rounders around the league might take a little time also as agents actually are loathe to be early in that slotting.
