I agree. Better talent with the three they drafted. But can they be ready to play if needed? With Brown out two games it is likely they need either Allen or Demby to be a game day active in weeks 1 and 2.
I would expect Noteboom and Allen to get a lot of work at LT and C respectively in preseason. They will give Blythe more work at RG as preseason goes on and it is also likely that Whitworth and Sullivan play very little. So Noteboom and Allen will have every chance to get a lot of experience in preseason.
