Joe Flacco will be the Baltimore Ravens starting quarterback in 2019, period. Love him, hate him or indifferent, the ten year veteran and former Super Bowl MVP will be under center on Week 1, barring injury. An ill advised extension means that jettisoning Flacco would cost the Ravens a net negative of $4 million in salary cap space due to $28.8 million in dead money remaining on his contract.
The backup quarterback job is a different story. The Ryan Mallett expereiment has seemingly run its course. Mallett is an impending unrestricted free agent.
