MINNESOTA VIKINGS: Pat Elflein, C, second NFL season. Elflein helped make a dramatic difference on the Vikings' O-line as a rookie, with Minnesota cutting its sacks allowed from 38 in 2016 to 27 in '17, while the running game jumped from 32nd-ranked in '16 to seventh in '17. And I think it was largely because of what Elflein brought to the table. Presuming he recovers from a fractured ankle suffered in the NFC title game and a shoulder injury that occurred in December -- he's aiming to be back by training camp -- we should see Elflein continue to thrive.
