Here's the 2010 depth chart for comparison:
Vols' depth chart announced; Williams at tackle » GoVolsXtra
The 2010 team had a very inexperienced offensive line (I seem to recall it was led by Cody Pope, a converted dlineman). As a matter of fact, three of our current olinemen (Stone, Fulton and James) were starting in their second college game. The 2013 team has a very experience offensive line.
The 2010 team had an inexperienced quarterback (Simms). The 2013 team has a somewhat-experienced, though unproven quarterback (Worley).
The 2010 team had an inexperienced (though a pleasant surprise in that game) running back in Poole. The 2013 team has two experienced backs.
The 2010 team had one experienced receiver (Moore; Jones was out with an injury), an experienced tight end (Stocker), and two green but talented freshmen (Rogers and Hunter). The 2013 team has some talented, but green, receivers.
The 2010 team had a relatively-experienced defensive line, plus a promising juco transfer (Malik Jackson). The 2013 team has an experienced and deep defensive line.
The 2010 team had an experienced linebacker corps (led by Reveiz and Frazier), but lacked depth. The 2013 team has an experienced linebacker corps, but similarly lacks depth.
The 2010 team had some experience in the secondary (Evans, Anderson and Jackson) but lacked depth. The 2013 team similarly has experience in the secondary, but lacks depth.
