That's code for "I hate Matt Schaub"
Even though Matt Schaub completed as many passes of 20+ yards in the league as anyone, they're thinking Kubiak's offense suffered because of Schaub.
When in truth, the offense only really struggled last year... it was because of Schaub though.
We ran a lot more boots, I think, with Carr & Sage. Even scored a couple of TDs with the QB rushing off the naked action. We also ran a lot more boots with Schaub prior to 2011. Most likely because of his foot but he also used to fade back on those boots instead of coming back to the LOS for whatever reason.
Anyway.... Flacco may not be a "mobile" QB, but he should be able to get the job done & your offense will most likely look like ours did in 2009~2011
