bortles wasnt as bad as many are making him out to be, when he played mobile and used his feet he made things happen(see: entire playoff run) and looking at the numbers he was pretty efficient, they could do much better but they could also do much worse. his career statline looks quite a bit like joe flaccos but with some pretty solid rushing numbers, and in the playoffs when they began designing qb runs he looked far better. i see the jags in the same light as the ravens around 2010 when we signed boldin and our offensive weaponry began to heat up, great defense, great run game, efficient qb with sporadic moments of big play and bonehead play, some solid but not spectacular pass catchers, the one difference is that we had an excellent OL up until 2013 and the jags OL needs work. and with this contract, the jags can actually make moves, unlike the ravens when they signed flacco.
i see nothing wrong with the bortles signing, and if the playbook is tailored to his skillset then he can be efficient enough to win, as long as you arent asking him to win a shootout with brady.
