Agree. I have every confidence that RK would have seen out his final year, even if everything in football recommends caution and scepticism.
Also doubt Les Reed would have come under much criticism if Koeman didn't sign a new contract. Koeman was pretty transparent from the day one that he would honour his contract, giving no real assurances beyond that. No more, no less. Three years is an eternity in management terms. Rather more likely, there would have been an acceptance that we were fortunate to enjoy his services for so long given his enhanced stock and reputation.
Those claiming Reed was in a thankless and impossible position are risible and weasel-worded. Reed had choices: he played hardball, betting on his ability to find an effective successor should Koeman not back down -all of which is fair enough. But by the same token, he'll be judged on that decision.
