Ignore the practice reports all you want. All the people that cover the team said JG is the heir apparent. They all agree JG has a stronger arm and was more accurate. No the reports did not rank the qbs each practice. There were double digit practices where the writers said Dobbs and JG looked great with either no mention of the other two, or they mention that the others didn't look as good. There were literally two or three times they wrote that QD stood out. After fall was over all the articles that came out say they believe JG is the qb after Dobbs and Dormady will back up. Those are facts. Sorry if they don't fit some of yalls confirmation bias for Dormady.
Here is just one example.
Every SEC East team's QB succession plan
TENNESSEE
Starter: Joshua Dobbs, Senior
Backup: Quinten Dormady, Sophomore; Sheriron Jones, RS Freshman
Redshirt: Jarrett Guarantano, Freshman
2017 commitment: C.J. Lewis (3-star)
Overall: As long as Dobbs is healthy things will be fine in 2016. There are plenty of questions surrounding Dobbs ability to make tough throws, but hes a strong competitor and leader with pluses that far outweigh the minuses.
If Dobbs gets hurt, the Volunteers have some depth. Dormady got into a couple of games last season and hes a pocket passer. Jones redshirted, but hes the mobile threat of the two backups.
Guarantano is the quarterback of the future and would probably benefit from a redshirt.
