The Bears only returning starters are OTs Wright and Jones and it can be argued that Jones could be replaced. What can Armagadje bring? Yep, a question. Maybe he can transition to LG while Braxton starts or moves to swing OT.
As for Center, the Bears do have Ricky Stromberg and Bates under contract but I am curious as who coach Dan Roushar would target if Poles spends cap for Center. Bates could end up a IR settlement casualty before the season starts too, so this position needs some deep diving. Roushar is known for developing lineman. His Saints acquired and C Max Unger in the Jimmy Graham trade and Unger became a probowler and the center piece for the Saints line. Unger was already developed, so I can see the Bears going this route. Drew Dalhman is a developed outside zone player, but would he fit Ben Johnsons attacking gap scheme or does Ben change to outside zone like the Bears and Roshar are already used to. Coleman Shelton is outside zone and is already comfortable with Caleb, so he could be the guy too. To me, this a plan A and B at Center
Now for the rest. The Bears should have choice 1 or 2 for an olineman in the draft. LT- Will Campbell should be a no brainer and I'd leave him at LT. Every report I have read or heard says this guy is a footballer and polished. I hope to find time to review thrse top OT and DT options and see myself. Round 2A, get a Guard Milum or D Jackson, 2B take a DT like D Walker or Alfred Collins DT Texas to rotate with Billings while Dexter/Pickens man the other spot. Round 3, is there a DE worthy like Ivey or Gilliloutte? Or do they take a RB like Kaleb Johnson Iowa who is power and agility at 6' 225 and gives the Bears a one two punch.
Sign another FA Guard like Zieter to challenge a starting spot and the line is in good shape. Round 5, take a developmental C, seen a handful of names. The last major piece is if there is a way to get a stud DE through trade or fa to pair with Sweat. If that happens, the Bears on paper are favorites again lol.
