MIAMI -

The Dolphins wide receivers have attracted a lot of attention since the start of training camp. Miami is happy now it's for positive reasons.

As was depicted on HBO's "Hard Knocks" throughout training camp, there have been questions about the group's ability. But a lot of the questions were answered during their record-setting performance last Sunday at Arizona.

After catching 12 passes for a franchise-record 253 yards, Brian Hartline now leads the NFL with 455 receiving yards. Davone Bess' performance in the 24-21 overtime loss against the Cardinals was easy to overlook, but he had career-high 123 yards on seven catches.

And now the Dolphins have signed Jabar Gaffney and hope they have solved the depth issue. Gaffney led Washington with 68 receptions last season.

Miami plays at Cincinnati Sunday.
