Brampton is in prime position to pick who they want and not pay a huge price.
That's perhaps true for a more middle tier guy like Swick, but the elite OA's will always garner a huge price because there's only a couple of them. Not to dismiss your argument, but we hear the same thing every year and the elite NHL drafted guys don't see an OA discount at all.
Dylan Wakely already went for a promising 2023 first round pick and 2 other picks. Guys like Owen Allard and Brady Stonehouse are almost certainly going to match or exceed that return, with the former being a Team Canada junior caliber player. The same could be true for other top OA's like Karabela, Smith, McCoy, Delic, or Misaljevic, depending on what kind of seasons they have and whether they are available or not.
I see Brampton and Kingston both looking to add two OA'S, (one being a goalie for the latter). Brantford, Sarnia, and Saginaw have opportunities for big upgrades on their current situations. Oshawa and London both have guys off to really disappointing starts, which has to be a concern. Then, of course, there are injuries. There will certainly be market outside of Brampton.
