Gannon is the decider, now he must have felt comfortable with starting Tune and evaluated him better with upside then the old colt, before trading For Dobbs and cutting Colt.
either way they competition continues into the regular season. May the best man win.
I think it's clear there was no comfort with what they had. The first team couldn't move the ball in preseason, they probably couldn't move the ball in practice either, the offense simply wasn't working.
They asked the OC if he had any ideas and he was like "there was this guy in Cleveland... he never played but he was seemed pretty smart, knew the plays at least, lets bring him in!"
I'm obviously being glib, but I doubt that take is far off. The 1st string offense was putrid in preseason and I think in their desperation for an answer they went looking for someone who "knows the system" and was available on the cheap.
However.... Dobbs is 28 years old and has been a 3rd string and practice squad guy his whole career. The whole situation screams of desperation.
