Vowles apologizing to Mick Schumacher and back-tracking a bit. Still learning on the job as a team principle. Obviously he was right, but the comment was unneccesary.
I think it's great that Williams took one of their academy drivers. It increased the credibility of the program. Rather than detracts, if Volwes had chosen a Mercedes or Red Bull junior/reserve.
The extra sponsor money is a bonus.
Ultimately though, if Vowles was serious about maximizing points scoring in the remaining races, he'd been better of running Lawson for 8 out of 9 races if Red Bull needed him to fill in as a reserve. It would be a bit of a mess, but surely Lawson would've scored more points.
