I agree with all of that.
With the QB run-outs, it's: run funny; put your head down and start shaking your head halfway to the huddle; clap your hands; hunch of over.
No variety.
The biggest issue with commentary is how it's being written and programmed, and that's evidenced by all of the strange generic lines. They've recorded tons of last names and all the team names, yet in situations where they should be said a generic line is spoken instead. Here are some examples:
"The defense lines up in..." = wrong
"The Cowboys line up in..." = right
Kicker comes out to kick a 47 yard field goal, nothing is said = wrong
"Smith in to attempt a 47 yard field goal" = right
"The quarterback made an excellent throw there" = wrong
"Manning made an excellent throw there" = right
(2K football had great system in place to handle this exact type of line and it was smooth)
There are all sorts of spots like that. Bringing in full-time guys will get you more lines, but it won't fix the script-writing or the programming that's holding a lot of things back.
