I don't know with Bass. He was undrafted but performed well when given the opportunity. Some players just slip through the cracks. Maybe he's the next Steele.
But if we only had Bass, I'd be more inclined to spend two of our top three picks on OL. However, we also have Richards who played well. I think we can take a shot at finding our LG/LT combo with Tyler, Richards and Bass this year and if it doesn't work out, then address OL early again next year. I also think adding a player like JPJ/Barton/Frazier would increase our options since they also can play guard. I don't like having only Hoffman as our center option, but that doesn't mean that he can't progress and be up to the task, allowing the rookie to play LG if that's where he's needed more.
We eventually have to trust players we drafted like Richards to contribute, not without some degree of fallback but we can't spend premium picks on every position.
