Assuming Blake told Bob as soon as he knew and didn't break any contract terms, I think they both chose one of the acceptable routes. If I were Bob I might have chosen to go meet with Blake to better understand and see if I could fix the deal. If Blake was operating within his contractual rights he did nothing wrong, nor did Bob.
I can think of two high profile teams that have done this. First, when Mike Neff let Don Schumacher know he was driving for JFR the following season, Don let him go them. Also, when Jimmy Prock let John Force know he was going to DSR the following season, he was also let go then.
I’m just connecting the dots. With Alexander leaving, BVR has a second car and crew with no driver or funding. With Shawn Reed splitting with Paton racing, I’m predicting that Reed will be behind the wheel of the former Alexander ride with Hughes Oilfield Transportation as the sponsor.
