In terms of picks for Erie, according to the database over the next 4 drafts. 2x 2nd rd (1 is a conditional), 2x 3rd rd, 5x 4th rd (1 conditional) and 4x 5th rd. They aren't too stocked so would imagine if they want to boost in other areas too they need to increase quality of players.
London and Flint could easily top that with picks, as for eastern teams if they want to make a run Niagara and Kingston have the assets. Outside of Kingston all those teams are closer to home. Personally between picks and prospects Flint may be the next best for Musty outside of Erie they have Mania plus the assets.
As for the rest it is 100% on Musty what happens, the team included owner has told the agent if he comes he will be in the line up immediately. Grier has said it hasn't affected his development at this point but could soon. If he wants world juniors he needs to be back ASAP , needs to play.
