I actually do agree with you there is a line to be drawn - can't go Aliadiere each time.
But as for the core issue - I see things differently.
Ramsey's been here 7 years and was mostly shite (and therefore, you'd have us think, he is also expected to be so in the future)? So - what is it exactly that happened last year? a divine intervention? a purple patch, by the end of which Cinderella went back to rugs for good? and what about yesterday? what about injuries? what about that injury (and a 3 year recuperation trail give or take)?
This is not against "I rate consistency" point - sure, I rate consistency as well. This is about individual players development path and excluding surprises, late bloomers, etc.
See again Coq: came from nowhere just days ago, yet in the last 3 months he's as consistent as can be (yes, we do need to look at it in years, not months. Still this amazing phenomenon - from thin air to regular 7-8 performances week in week out is telling).
Again - these are but examples. The main issue is - do you believe, and do you leave room for - a player clicking after a long search time, hatching after a long incubation, or you look at them all via "factor 1,2,3 at level x, indicates that" is the universal formula. If so (the narrow choice): dump Jack asap? Chez? and surely Welbeck, and why on earth were we wasting time on the likes of the corporal, and Theo. Theo! 🙂
EDIT: is it me, or this was moved here from elsewhere (and why? Because Ramsey's the example?)
