Just a break down based mostly off of things heard through go vols extra and coach interviews.
-Ferguson was complimented by CBJ during fall camp a day or two as having "really stepped up." This is why most assume he has the advantage over Dobbs.
-Ferguson supposedly has the strongest arm of the bunch. Some have compared him to Tyler bray in that his arm is strong enough that he likes to challenge the defense as take some risks.
-Ferguson is a scrappy kid with a winners mentality. He won almost every game he's played since middle school. In several interviews before he stepped on campus, he stated his main focus was to "get on campus and win the starting job."
-Ferguson competed and did well at the Elite 11 competition, despite having a broken thumb on his throwing hand. He showed some grit and determination in that.
-Trent Dilfer, who saw both Dobbs and Ferguson at the Elite 11 described Ferguson as scrappy a "gamer" who finds ways to win and Dobbs as a "silent assassin" and very cerebral.
-Dobbs showed out during the open practice with a nice deep pass and a scramble where he shook Jaron Toney. Worley afterward complimented him and noted that they've seen him have some nice scrambles and moves throughout camp.
-Dobbs and Ferguson have similar straight line speed, but Dobbs has been described as more athletic and fluid. He has a bit of shake and bake in him, but he is by no means Mike Vick speed wise. Think more along the lines of Chris Leak.
-Dobbs may be more athletic, but Ferguson definitely has the speed and athleticism to run the read option and pick up 4-5 yds when the defense leaves it on the field for him or exten some plays with his feet to make some throws. He's still a pass first guy.
-Dobbs ran the scout team offense last week, mimicking Mariota for the defense.
-Coach Jancek commented last week that Dobbs have the defense some fits running the scout team. Said he took off with the ball a few times and looked athletic.
-Dobbs has been on campus longer and supposedly has the playbook learned down pat (though he hasn't always executed in practice). Not surprising from a kid who learned his high school playbook in a day.
-Ferguson and North practiced a bit together before stepping on campus in the spring/summer. They may have some chemistry because of this.
-Dobbs received some first strong snaps at some point in camp and made a few positive plays, but he fumbled a snap and has supposedly had some trip ups with such things throughout the fall.
-The coaches have made the QB live on a lot of Dobbs's snaps throughout the fall, presumably to gauge his scrambling ability.
-Both Dobbs and Ferguson have split reps with the third team for 90% of camp.
Those are all just snippets that have come out through various media sources, but obviously none of us know how they look in individual drills or in practice for the most part. It's hard to say definitively who looks better in practice or is ahead on the depth chart because neither has gotten many reps ahead of another and we haven't gotten a chance to see either live against a starting defense.
