I would be surprised to see Barker slip out of the top 5 IMO. He has tons of upside. A down year didnt drop Nathan Hortons stock last year.
The only chance that Barker might slip is because it's more and more likely Wes O'Neil well opt in. O'Neil is more of a here and now impact kind of player. Barkers defensive game needs alot of work. But the upside of a dominant force on the back end is there. O'Neil on the other hand. Makes it look easy out there, he shuts down NCAA teams night in night out. I saw him last year in Green Bay alot and a few times this year. His offensive game has progressed slowly but O'Neil is so smart and so good with the puck it could devolope.
Schremp should not go passed the #6 slot. He's not a bad boy as we all think. Schremp has just amazing skill. I would take him #5 if I was a gm in fact.
Schremp has amazing hockey sense, and just as good hands. If he has the puck, he's one of the most dangerous players in this draft.
Barker is an offensive defensman, with great size and good skating ability. His offensive game is furthur along then his defensive game. He has been improving though.
O'Neil, huge, good agility and skating ability for a man his size, hard shot, passes well. I see him more of a Mike Rathje though, were he is put against teams top pairings and well just shut them down. Depends what you want. O'Neils stock is rising IMO, and Barker has slipped abit.
