It's obvious you don't know what the strategy is.. This is the strategy-

Obviously Merling and Langford won't be playing the same position, .. And in case you didn't notice, we needed alot of O-line help.. Jake Long and Murphy/Thomas wont be playing the same position.. Our biggest need was o-line and O-line depth.
And Mormino sucked hard before he got hurt.. he got annihilated in the preseason games, He was weak and slow, just getting killed out there. And Smiley has shown to be injury prone. So 2 guards were needed ! And we got two good ones late. One who was projected by some as the 2nd best guard i the draft (Murphy), and another who was the 2nd fastest lineman at the combine (Thomas)
