The 3 they signed today are RBs Jalen Parmele and Lex Hilliard, and DE Lionel Dotson. Parmele and Hilliard were 6th round picks, while Dotson was a 7th rounder. The terms of the contracts weren't disclosed, but it's likely they each signed 3 year deals. As soon as I hear or read any figures, I'll pass them along.
The Dolphins now have 4 draft picks signed while no other team in the NFL has even signed one. Kudos to this front office forworking quickly.
The Dolphins also added an undrafted free agent, center Matt Spanos. Spanos is out of USC and started 9 games for the Trojans last season.
