The only thing I'm sure of is that Morse will be at Center.
If I had to guess I'd go
LT Dawkins
LG Spain
C Morse
RG Long
RT Ford
From what I've read Ford is a better pass blocker than run which will come in handy against edge rushers that don't traditionally come off the left side.
In the current NFL landscape, the overwhelming majority of top pass rushers play left defensive end or linebacker, which means they line up across from the right tackle. That includes J.J. Watt, Von Miller, Khalil Mack, Justin Houston, Joey Bosa, Vic Beasley, Cameron Wake, Cliff Avril, Markus Golden, Ryan Kerrigan, Carlos Dunlap, Cameron Jordan, Jason Pierre-Paul and Danielle Hunter, a 22-year-old rising star who recorded 12.5 sacks for the Vikings last year. Ford is a massive upgrade over Mills.
