Blake Bortles has never been and will never be the answer at the quarterback position in Jacksonville.
A solid defense led by a star cornerback in Jalen Ramsey needs to be complemented by a capable-enough offense. Bortles just can’t get the job done. Foles is a proven winner and would stand a much stronger chance of leading the Jaguars to a playoff berth of some kind. Assuming wide receiver Marqise Lee comes back healthy after missing all of last season, and the Jaguars possibly draft another receiver (or a tight end), this team could be one of the biggest sleepers of the 2019 NFL season.
If I were Shadid Khan, the owner of the Jaguars, I would be doing whatever I could (within reason) to acquire Nick Foles. Search for your next franchise quarterback in a future draft and pick up a proven winner now.
