Sam usually does well after making a mistake. Hopefully he (we don't run the ball, so it really just comes down to him) can capitalize on that great defensive series.
But it wasn't a designed run. Why would he have run right after the snap? They called a pass that required a second or two of development to work. That's not on Howell.
Trying to be as objective as possible, where does Sam Howell rank in the league right now in terms of performance? #10-15? There aren't that many QBs I would take over him today and he has potential to be even better.
