I think it was the scheme. Allen had a scheme he basically played a 2 LB system and Baun had no where to shine in scheme DA ran. Also I think we get so focus on external events that we never know Baun might stepped his game up, knowing he had a great opportunity. I'm personally happy seeing him succeed he always seem to have a great attitude and took advantage of his limited opportunities here
What’s funny is that the Eagles more or less put him in the same scheme that he wasn’t good enough for here. You can call the Eagles a 3-4 base defense, but they played their nickel defense all last night, which is basically a 4-2-5.
