He's not on a crusade, it's a matter of opinion and he may very well be right.
The big difference between Eiserman and the player that Marner is would be that Eiserman is a pure sniper. He doesn't really need to go to the dirty areas to score.
I mean if we get Catton... great. Iginla.... great. Same with the others. Eiserman to me, represents the highest ceiling. Even as a permimeter player (such as Brett Hull) he could still be a superstar. If he's coached right, he could be phenomenal. I'd rather go with that despite all the warts.
My biggest concern with Eiserman is a lack of development this year. He doesn't look or produce differently than he did in his 16-17yo season and I think that needs to be factored in when we're discussing what his upside is and what his developmental trajectory actually looks like.
Statistically speaking, he's been fairly stagnant in the goalscoring department in both USHL and USNTDP games. He's got great draft year numbers, but he had a *phenomenal* D-1. If we saw notable improvement in his playmaking or two-way game, this might be less of a concern as we'd have an easy explanation for that plateau. However, by most/all accounts that I can find, this doesn't seem to be the case. Neither does quality of line mates tell the whole story either. His game hasn't grown or evolved offensively (or otherwise) and there's a real risk that he may just be an early bloomer that can produce against weaker competition.
I'm fine with recognizing that he has big upside as a goal scorer and I like that he's very young for this draft. However, I don't see much upside in other offensive areas of the game, as a physical presence, or as a two-way forward. If his goalscoring doesn't translate or if he's plateaued, there's absolutely no B-game to fall back on. Big risk potential that other top-10 forwards, including Catton, just don't have IMO.
