Wait what? He was healthy last season. Played 100% of the snaps in all 3 playoff games too. Feel like Keim goofed and is talking about someone else or made a mistake there.
I mean, he does have the prototypical Tackle body-type. 34-5/8" arm length. 84" wingspan. 10-3/4" hand size. All of those are like 75% or better for Tackle. His athletic testing was in the 90+% range too. His body has better prototypical Tackle measurements than Laremy Tunsil or Trent Williams. He's got great tools to work with.
For reference, Josh Conerly might have slightly sub-par tools to work with (besides his fluid athleticism which is a big plus). But the 2025 combine was heavily criticized for messing up the measurements for all of the OL. The Senior Bowl gave Conerly longer arms than the Combine did. So who knows. His wingspan isn't the best either. If we average Conerly's measurements, then his arm length is 33.75". There have been Tackles that still excelled at that. Joe Thomas was around there (he had another combine measurement error but later measurements came back better).
Conerly could still work out just fine. But moving Coleman off of Guard when his rookie year was good (for rookie standards) and had such good measurements always rubbed me the wrong way. Conerly at least has much lighter feet than Coleman.
