It's hard to get a good read on much after only three games but, here is what surprised me so far from what I thought coming out of preseason.
Clay is giving us pretty much what we had hoped for from Keller. Martin has really improved in pass protect. Tannehill has been better earlier than I thought. DT has played pretty well. Grimes has been great, and Carroll and Shelby have played well
On the bad side (for now) is Clabo, Miller, run blocking by all, run D by all, OV, and Jones.
