...they are the same age, both in 3rd year of OHL eligibility. The fact that he played his 16 year old season in the CCHL and Spears played his first year in the OHL has little to no effect on his development this year. Seems like a borderline irrelevant fact that's being used to grasp at straws.
Are you saying there's no advantage to repeating the same level a 3rd time vs a 2nd time? I would suggest the player repeating a 3rd time has an advantage, even if it might me a small one.
Not to turn this thread around, but the fact that Speers is more efficient at racking up assists on the PP has little bearing on his prospect status. Speers numbers are actually down from a year ago, which likely has more to do with the quality of team rather than regression. There's a reason teams employ scouts and don't take the simple approach of sorting the points column like many HF posters do.
Top-5 in goals and top-5 in shots in the OHL. Even from a stats perspective, Senyshyn displayed very good progression from year one to year two. There's an obvious tools package to work with, which I'm sure played a big part in him being ranked much higher than Speers last year (and taken higher), despite being the lesser player on the same team.
