I think its reasonable to assume in year two MHJ makes a jump in terms of performance, but I guess the question is, how much of a jump will he make?
What are your guys' (and the ladies as well) expectations for him next year in terms of yards/TDs/YPC/ etc?
He's going to be better yes.
Again the things IMO he HAS to improve at
1) Catching contested balls, high pointing, going to get the ball
2) Getting more separation, better routes etc
And I might as well add run after catch which he never did this year
