The highlighted parts are my response.
I can show you a player who's had nearly 2/3rds of our touches in an opponents box, single-handedly.
"lesser quality players" is a bit of a stretch, and sounds like an excuse as to why a striker isn't/hasn't scored as many goals as they'd hoped. His role.. is to score, whether creating himself (which he doesn't do), or stretching teams (which he also doesn't do) thus enabling a ball in from the wide area.
He scores, finishes.. however you want to put it.. and does absolutely nothing else, doesn't stretch teams. Doesn't have the pace to play that counter role, doesn't have strength to play a "target man" role, doesn't have the nous to operate up top on his own.
Is that a player worth 13M?
We're sheffield united.. not Man City.. We can't afford to spend 13M on a single player with a view to them becoming a more "developed player".
EDIT: I forgot to mention too. You're mentioning XG etc. They're slightly misguiding - he's scored 4 penalties.. and four goals in a single game. so one other goal from those. Not that great when it's explained that way.
The stat i dont have to hand is xT, expected threat of the chances which have been created - which would create more of a talking point.
In regards to the lesser quality players, its correct though - they do have less quality with their players, hence where they are in the league. we are where we are due to big moments from players creating things out of nothing for each other. (if anything an argument would be that they would be much lower down the league if it wasnt for their keeper who has prevented 9 goals xg wise this season, so the quality of their other 9 players is massively questioned here)
i was using the championships goals, but take your point - however ill play devils advocate - Leon Clarke scored 19 in 39 games for us, he also scored 12 in 37 games (Fulham and Hull removed) and we were all extremely impressed with him that season....
In regards to the money, the journos are always miles off - as per what wilder, hecky previously, has said in their pressers. It all comes out in the finances at the end of the year and promotion bonuses will distort things. We live in a time where strikers cost money (Rhodes £10M?!?!) Look at Boro, selling Latte Lath for £18 million to the MLS, lad hadnt scored a goal all season prior to the one he scored vs us. Lath is a 1 in 4 striker, currently 4 years older than than Cannon, whos running at 1 in 3. Strikers are expensive and god knows how we managed to sign one on a free whos already scored 6 for us this season - so 13M (all in) for a player who could quite realistically fire us to promotion is sensible business for top of the league.
as someone has previously stated, we could have signed Ashley Barnes....I understand the skepticism of this transfer, especially with the money quoted however we arent a spending club, this isnt the norm for us to be doing this, its against our nature, so of cause there will be concern. Personally, i couldnt name a better option for someone who is tried and tested in the championship (i would sign other players to play alongside though such as RJJ, BBD, Barry etc)
