Get Rid of These Quarterbacks?

The quarterback is perhaps the most important position in all of football. He is the on-field general and helps run the offense fluidly. However, there are some quarterbacks in question that are not doing so hot. Should the following quarterbacks be scraped?

• Carson Wentz, Philadelphia Eagles: The quarterback facing the most scrutiny at the moment, Wentz has only completed 58.4% of his passes this season. Wentz has also thrown 12 INTs this season and has a rating of 73.2 this season. It doesn't help that Philadelphia's offensive line (and team, in general) has been battered by injuries; Wentz has been sacked 32 times this season. Still, a part of why Philadelphia is below .500 is due to Wentz making costly mistakes from time to time.
  
• Jimmy Garappolo, San Francisco 49ers: I was the biggest fan of Garappolo. I believed that he was good enough to lead the 49ers to another Super Bowl. However, it doesn't help your team when you get hit with injury after injury. This is especially true when you're playing in the toughest division in football. His most recent injury is an ankle sprain, where he'll miss multiple weeks.
  
• Sam Darnold, New York Jets: Tank for Lawrence, right? The Jets should honestly be scrapped altogether at this point.
