It's a tricky one to gauge re their decision-making on this. If the opportunity to invest happened quickly, perhaps they thought that the due diligence required before making choices on manager would necessitate more time. And I can imagine they also thought "Let's meet with the incumbent manager, and see what he has to say" which surely is only respectful and right. Fortunately for Bruce, his soft skills are one of his assets so I can imagine him giving a good account of himself. If they're happy for us to have a stable season without worrying about a promotion challenge, he will have been able to sail through the meeting. If they said they expected the team to be challenging, a bit of waffle from Bruce may have saved him.
Henry would have been a big experiment for both parties, I don't think he's done enough to deserve to manage us. So, as much as Bruce's football frustrates me, I can understand his staying on and I just hope he hits on gold; accidentially or otherwise through promoting youth - one of his hitherto key failings and sourcing good loans from his book of contacts - one of his key strengths.
