Wow that is so extraordinary as to be unbelievable. That a coach wouldn't sit down with ANY rookie to get them started viewing tape is beyond belief. Then again, we're talking about Da Bearz, of Jay Cutler fame (GB's "other" MVP), so nothing is too strange.
I didn't see the article you reference. If you have a link please share.
Staying with film review - I think the right way to do it is sit down with each rookie and their position coach and go through film, showing what the coaches are looking for, and what the player can look for in future film reviews (reviews players do on their own). These film reviews strike me as really important.
In that notorious NFCCG loss to the Hags in 2014, the Hags executed a fake FG for a TD just before the first half. At the time, the Packers were dominating, and while it was disappointing it wasn't the end of the season (world) yet. We all know how that game ended.
But the fake punt came from film review by the Hags. I forget the LB's name, but they noticed he always runs at the kicker from the same position on the line and the same angle and pays zero attention to a possible fake. Add that to the fact the Packers should have been looking for a fake and you've got - a failed play by GB but excellent execution off film review by the Hags, much as that pains me.
