Weaknesses

Average overall agility trying to connect as a run blocker. Pushed back off the ball when opponents get to his frame. Stronger edge defenders can throw him off more easily. Can get a bit high off the ball and trying to drive. Has trouble driving when his base gets too narrow. Inconsistent quickness on reach blocks. Can be better identifying a downhill threat when working to the second level. Will lose his coordination/footing at times. Needs to keep his feet when connecting on the second level. Appears to have some stiffness trying to torpedo low off the ball in short-yardage situations. Pass sets can be too shallow and lead to rushers getting around him. Doesn’t stay engaged as well in pass protection. Can be more prepared to slide his feet as a pass blocker. Feet can be too choppy as a pass blocker. Slower reacting to quicker inside moves. Hands need to get lower to stop dip moves. Had some struggles versus the talented defensive front for Oregon (2025).

Conclusion

Overall, Dunker is a gritty offensive lineman with great raw strength and very powerful hands to attach and drive. Issues with foot agility, inconsistency in pass protection, and struggles versus better opponents aren’t enough to automatically move him to guard.
