I think their plan should revolve around how they feel about their line overall. If they think they can go into the season with a line of Walker, Jenkins, Myers, Rhyan, and Tom, then they can probably stay put and take the best guys they can get in Rds 2-4. The higher rated guys are more ready to play right away, so move up if you have to have an immediate starter.
To me guys like Guyton and Mims need more development so won't likely be able to start right away, but they have basically the same athletic abilities as the top guys and have similar ceilings. One of them will likely be there at #25. There are even guys in Rd2 that have high ceilings. Guys like Suamataia and Amagadjie could be solid or better NFL starters down the road. Some even like Rosengarten, Puni, and Fisher that way.
It's a deep group like Mark said. To me it all depends on how Gute feels about the current group and if he thinks he doesn't need a right-away starter.
