Watson only had a 49% win record for Salford. For context, Woolford's was 48%.
You hired him, presumably, based on a GF run that was created by Jackson Hastings and Joey Lussick and a cup final appearance that we didn't win after having a fairly easy run to it. Watson thought he would leave while his stock was high, which is fair enough but if you think that for some reason your fortunes will change overnight you may be in for disappointment. Watson when at Salford had a real reluctance to promote the good quality young lads from our academy, and it seems that continues at your club. This isn't a bitter 'rub it in' post from a Salford fan either by the way. While we would have been happy for him to stay at the time, the way he manufactured his exit showed a different side and we wouldn't have him back for anything.
He may come good for you, but I think his success (the small bit he has had) with Salford relied heavily on a few quality players in Hastings, Lussick, Evalds, and a pack punching above its weight rather than coaching genius. He did seem to have a knack for getting the most out of players that were seen as average at other clubs, but once again a lot of that could be attributed to raising their game due to the likes of Hastings and Lussick pushing them around the park.
He may come good, but I think you'll need to stick with him for a while before you see a great deal of improvement. Whether you all have the patience for that is another matter of course.
