I think more important than changing players would be replacing Shula with a competent OC. Honestly, even with Moton, Gross, Icky, or whoever you want to put at RT, prime Von Miller was pretty much impossible to stop. The ridiculous part was putting a bottom 5% OT on an island against Von Miller without any TE or RB support/chip.
Any version of Steve Smith like a poster stated earlier, this board, fo, and wannabe analysts all thought it was a good idea to cut him and acted as if he was going to hinder that 2015 team.
you think any db in the world wants to face Steve smith in the playoffs let alone Super Bowl ? Broncos bullied our wrs and o line and we never recovered
luckily the falcons followed that embarrassing 2015 Super Bowl loss we had with one of the worst choke jobs in history, I couldn’t sleep for weeks after that superbowl(figuratively speaking)
