9. Miami Dolphins offensive line: Center Mike Pouncey is the only certain starter returning from last year, and he is trying to recover in time from hip surgery. Having this line come together fast will be the challenge. Branden Albert is a lock at left tackle, as is Shelley Smith at right guard. The hope is that Ja'Wuan James starts at right tackle, but the Dolphins brought in veteran Jason Fox for insurance. Third-round choice Billy Turner will battle Nate Garner at left guard. Veteran Daryn Colledge received a $2 million contract to be insurance at guard and center.
10. Carolina Panthers wide receivers: The Panthers parted ways with their top four wide receivers from 2013, a list headed by Steve Smith. Quarterback Cam Newton has to see if Jerricho Cotchery, Jason Avant, Tiquan Underwood and first-round choice Kelvin Benjamin are good enough to upgrade the unit. Cotchery is expected to be the No. 1 receiver, but every spot after that is open.
