We have struggled to handle QBs that can scramble, but if you think about it they also could throw. Christian and Streveler both can throw it. Broadnax is unproven in the passing game. Yes we have in the past struggled, but I would say it was more against duel threat QBs. The last QB that I can remember that was mainly a runner that hurt us was Bailey for UNI in 2015, the second time in the playoffs he was shut down. Just my opinion.
