I doubt at this stage that anyone is likely to change their minds re: the coaching situation.
Agree on the point by Once were Loiners on optimism rather than being die-hard fans of Smith. Some of the vitriol directed at Smith isn't fair: I read one comment on YouTube suggesting that it was JJB rather than RS who was responsible for our GF run a couple of years ago.
I think the problem with the debate is that there's no direct evidence that the coach is responsible for everything going on on the field. Certainly he's not making the handling errors or penalties that are killing us every week. But it is his squad, and the lack of depth and quality in some positions is down to Smith. Smith can influence the game through messages being sent out, half-time talk, and substitutions etc.
Looking at the squad, to be honest I expected more from the forwards. Penalties and errors are killing us because the forwards seem incapable of bending the line apart from the odd carry from Oledski, 5 minutes either side of half-time by Lisone. I'm not sure any of our injured players can offer us much more in this regard. Some of the signings, e.g. Goudemand and the extension of Bentley look questionable, even though both players have been decent for us, they are not of the quality demanded at a club like Leeds. Whomever is responsible for managing the cap made a big error in not signing a durable pack leader.
The spine is mostly fine, especially if Frawley makes way for Sinfield at some point. We missed Croft and his regular try assists. Miller, sadly, is the new Konrad Hurrell - a really exciting player when the team have their tails up, but when the chips are down he's got too many errors in him (I like Miller, and hope he can improve).
The first choice backline is very decent, but on the evidence of the season so far there is a major issue with depth. Roberts is a case in point; he's our first reserve, solid defensively, offers very little in attack, and makes more errors than any other player in the team (SL website). He's still young, but as our first reserve isn't offering a great deal more than Olpherts did. Edgell may have more time but he looks too small to have any real impact with the ball in hand. Some of the others we saw in the friendlies looked more promising; I don't really understand how the pecking order for younger players coming into the team works...
