I think its more a combination of the first two than the coaching. After having some time to cool down and reflect on the season to this point, while you can queston coaching and personnel decisions which all go hand and hand, what glaringly stands out to me is the lack of depth and talent compared to a lot of other teams I've watched.
RG3 was a slice of hope, a band aid on a wound that really requires stitches and an anti biotic. We lack play makers, beasts, explosive players, monsters at a position that teams fear and have to game plan for. Outside of RG3 there are currently no real offensive threats...the defense is also devoid of beasts and play makers...the line backers are slow, the defensive backs are horrid, the down linemen get little to no pressure. This team lacks depth and isn't good enough to overcome the injuries they have sustained. While I don't think the coaching staff is the greatest, I think they are good enough to get the job done if we had the talent to make it go.
Maybe it is a trickle down issue....maybe shanahan does need to be relieved of management and personnel gm autonomy. Maybe the defensive coordinator needs to take a hike, Idk....httr I love RG3 and alfred morris, and I hope they succeed here and their unique talents aren't wasted...RG3 looks like a once a generation or two kind of player....I hope they are properly utilized and get the most out of them.
