Depth charts are entertaining. Depth charts are instructive. Depth charts aren't usually accurate in real-life application.

These statements on their value can all be true.

Clemson released its opening depth chart Tuesday, headlined by the anticipated public confirmation that freshman Blake Miller is the starting right tackle.

Among the other notables was that fellow freshman Collin Sadler was listed as the second-string left guard, with veteran John Williams tabbed below in the "or" department.

We have expressed belief that Sadler's cross-training at several line positions over the last month reinforces our returns that he could be more than simply the second-string at one specific position.

Put another way, if Clemson promoted Miller to starter in search of its five best linemen, then Sadler may well qualify as No. 6 soon if not now -- which is why he is being groomed to handle multiple positions, just in case he might be needed there for an extended period.

Having two first-year freshmen feature this season on offensive line could come with substantial recruiting benefits.
