Hawaii had a highly productive group of receivers back in 2007 that actually resembles the Dolphin's group of receivers.
Hawaii had Davone Bess and Ryan Grice-Mullen (2 extremely good slot-type receivers with elite quickness and great hands). The Dolphins now have both WRs on the team and a very reliable Greg Camarillo.
Hawaii had a very physical WR in Jason Rivers. Rivers was a 6'2 WR with great heart who not only had soft hands, but also he blocked for other WRs on routes and would fight for extra yardage. I believe that the Dolphins have that sort of WR in Brian Hartline. also Patrick Turner could develop into a similar type of receiver given time and a bit of hard work.
The last of the 2007 Hawaii "dreadheads" was C.J. Hawthorne who converted from DB to WR in his senior season and contributed as a burner. Hawthorne was only 5'11 but he was FAST. We also have a burner on the Dolphins WR corp named Ted Ginn Jr. (Ginn is essentially Hawthorne except faster).
The 2007 Hawaii team also had Colt Brennan, who was a good QB and a heisman finalist. That being said, Chad Henne has the size, the arm strength and the instincts to put up Brennan-esque numbers with a similar set of WRs and a good O-line at his disposal.
I do realize that the 2007 Hawaii offense was a pass-heavy offense which didn't face elite defenses every week and the Dolphins are the polar opposite (Dolphins have a run first offense and they face elite defenses on a consistent basis), but here are the receiving stats from the 4 starting Hawaii WRs from 2007:
Davone Bess: 108 catches for 1266 yards and 12 TDs.
Ryan Grice-Mullen: 106 catches for 1372 yards and 13 TDs.
Jason Rivers: 92 catches for 1,174 yards and 13 TDs.
C.J. Hawthorne: 61 catches for 859 yards and 6 YDs.
