This is an interesting and unfortunate dilemma. None of Carson's fumbles have been particularly egregious on their own and it's a very recent problem. It's also too big of a problem to just overlook.
My primary concern in the short term is that Carson still looks like our best option to run between the tackles, while Procise, Penny and Homer all operate best in space. Just benching Carson punitively could potentially damage his confidence and aggression going forwards. Is it sufficient to make this a further emphasis in practice?
This issue also increased my concern regarding two longer term issues.
First, we continue struggle in poor weather more than the typical team does. As of a year or two ago Wilson was one of the most accurate QBs in the NFL in dry weather (#1?) and somewhere in the mid 30's when playing in wet weather (#37?). We also see our players slipping around in the first half on the road before they can change cleats at half-time. It becomes a pretty big problem when we're slipping around at home and struggling more than the opponent with Seattle drizzle. Maybe the players have too much agency in selecting their own equipment, maybe Pete lets them practice indoors too often at VMAC when it's raining outside, or maybe we've just ended up with a group of skill players who are best in nice weather.
Second, witnessing how well Kamara played puts our RB group in an unfavorable light. It is a deep group but I'm 10% less certain after today's game that that any of our current group is the kind of difference maker that we've been lacking since Marshawn. We've seen the Rams offense look mediocre without a healthy Gurley and the Chargers struggle this year without Gordon. I imagine our scouting department is paying extra close attention to the RBs on Saturdays.
