Let's see what random thoughts I've had after reading through this:
1) The contractor/brick question. diehard had a good answer for it, but to caveat, we might not actually be laying the bricks right now. Rather, clearing up all the rubble from the previous shattered attempts at building a foundation (hence Year 0), so we can start on a clean slate with Butch's style of players and system come 2014. To correlate, this could be indicative of why he burned Dobbs' redshirt and is saving Ferg.
2) What's the deal with Tennessee QBs and breaking their thumbs?
3) I think Ferg and Dobbs are legit, and both will see lots of playing timee next year. Personally, I think Dobbs' redshirt was pulled because he's a smart kid pursuing an aerospace engineering degree (and thinking about a future outside of football), and will mostly likely NOT leave early for the pros til he gets his degree, meaning more time in school and more time in uniform. Similarly, this will mean that Dobbs can play through the 2016 season, but Ferg will still be eligible to be the starting 5th year senior QB in 2017, and he might like the idea of providing that leadership, guiding the younger QBs, and showcasing his skills for a high draft pick in the NFL.
All in all... and as I aforementioned... I think they're both legit QBs. I think they are stronger and weaker in different areas, but when we start to alternate them in the games, it'll make things very difficult for the defense. I'm just excited for 2014 and on.
