Jack's end-product with us at PL level doesn't match up to Morgan's, does it?
They're pretty similar, especially if you ignore the pre-relegation seasons where Grealish was only just establishing himself.
What I meant by end product though is that both of them have the talent to push on. A goal&assist return of 1in 2 is very good but not elite and the ability is there to make that step up. 25 g&a isn't an unfair target for Rogers this season and is the sort of numbers that would make it hard to not have him be a regular part of the England team for the World Cup, especially given his record for England is also very good.
