I agree, especially with the short timing passes. However, does the OL give our RB enough time to release over the middle?
As far as being conservative, well Stubby's decision to come out and establish the run against Detroit's defense was either foolhardy or, as pbmax suggests, an attempt to avoid Rodgers getting run over by the pass rush. I tend to believe it's both and that is playing conservative, i.e., not playing to your strength.
