Assuming this is related to the Development Camp that will likely be held this week, here is a list of players I assume will be there that are Oilers prospects already:
Goalies
Nick Ellis(Providence, NCAA)
Zach Nagelvoort(Michigan, NCAA)
Miroslav Svoboda(Trinec, Czech)
Dylan Wells(Peterborough, OHL)
Defensemen
Ethan Bear(Seattle, WHL)
Filip Berglund(Farjestad J20, SweJ20)
Matthew Cairns(Georgetown, OJHL)
Vincent Desharnais(Providence, NCAA)
Caleb Jones(Portland, WHL)
William Lagesson(UMass Amherst, NCAA)
John Marino(Tri-City, USHL)
Markus Niemelainen(Saginaw, OHL)
Forwards
Tyler Benson(Vancouver, WHL)
Drake Caggiula(North Dakota, NCAA)
Evan Campbell(UMAss Lowell, NCAA)
Graham McPhee(USNTDP)
Aidan Muir(Western Michigan, NCAA)
Jesse Puljujarvi(Karpat, Liiga)
Aapeli Rasanen(Tappara J20, JrA Liiga)
Jere Sallinen(Jokerit, KHL)
Tyler Vesel(Nebraska-Omaha, NCAA)
Last year they brought 17 forwards, 10 defensemen and 4 goalies, so I'd imagine they go for something close to that again. My list has 9F, 8D and 4G; so I'd imagine they invite quite a few forwards and a few DMen. I'd like to see them invite Bonnyville Pontiacs D Brinson Pasichnuk, put up 65 points in 52 games in the AJHL last year to go along with 161PIM. Stat line is super interesting and he's headed to Arizona State next year, might be a chance to get a leg up on a guy who could be an interesting overage pick next June.
Also worth noting that in one of the videos posted on OilersTV Gazzolla says that medicals for this camp are scheduled for July 2, so I'd imagine we get the full list of invites tomorrow sometime. Good chance Puljujarvi won't skate at this either since he's recovering from surgery still.
