I don't know mate - I just think that if Kane just really focused on being a distributor, he'd be very good at it. We're seeing glimpses here and there of what's possible but I feel like he's being hindered in some ways because he's still trying to be a #9. He's just much more valuable to us as a player that solely focuses on distribution. He's not the #9 we need right now.
But then we wouldn't fully utilize his finishing ability, which is still top-class. You're right that his distribution is highly useful to us, but at present we still only have Sonny who can reliably stick the ball in the back of the net from chances Kane might create.
I still think the major difference is that we no longer have the free-form offense of peak-Poch era, i.e. Eriksen, Dele, Son and Kane at the height of their powers. Each of those players, plus contributions from wing-backs like Rose and Walker made us a formidable squad that could score and punish teams from a variety of areas. Once Eriksen left we had no-one who could distribute the way you're suggesting Kane should, and have still not replaced his creativity. Dele.. who the fuck knows what his issue is, but once upon a time he was virtually a second striker at times, supplying Kane with excellent service and being a target for clever passes himself.
With those key tools gone, Kane isn't getting service the way he used to. You mentioned how he can't beat a man anymore; he was never that good at dribbling past someone anyway. What he was great at was using his passing ability and finishing ability to create or score bags of goals in concert with an offense who could do the same for him when he found space. He was the world-class striker in a top-class offense.
Now he and Son are our only players of that calibre. One way to solve this is, as you say, to utilize Kane for his distribution, which means we are going to have to obtain better finishers for him to partner Son. Whoever we get on our budget will not be the all-round stars that he is, so would have to focus solely on finishing. It might work in the short term, I agree, but I also think it wastes the talents of one of the best strikers in world football.
I just think the better solution is to try to finally replace Eriksen, and keep Kane's qualities still in play at the front of the attack. At least long term.
