Updated PFF OL tells the tale

[*ochocincos*]

The starting OL's cumulative grades through 5 weeks (rank among position):
Jonah - 58.9 (59th of 72 OTs)
Volson - 49.5 (59th of 75 OGs)
Karras - 60.0 (18th of 38 OCs)
Cappa - 64.0 (25th of 75 OGs)
Collins - 53.2 (65th of 72 OTs)

So out of the group, Karras and Cappa are still sitting at "solid," Jonah and Collins are starter-level, and Volson is bad through the season so far.

This is based on the rating of:
80+ = elite
70-79 = good
60-69 = solid
50-59 = starter-level
49 or less = bad

This obviously means they might currently be better than what their cumulative grade indicates, but their bad performances early in the season are affecting their cumulative grade.
If they continue to improve as the season goes, their cumulative grade will go up too.
