With all respect, I just don't get the logic.
Botterill
may not be acting "in haste" to move Ristolainen now, because
if Cozens does well a month from now, it means Botts has another ~3 weeks (let's say to end of October) to address center depth (or Eichel RW as
@Chainshot noted) (or whatever the presumed "ready-now" roster return is from a Ristolainen trade). (???)
Why would such a delay be beneficial?
Does Ristolainen's trade value increase in the next 2 months? Highly unlikely in such a short time. If it did increase measurably in such a short time, it would seem the more prudent path would be to hold onto Ristolainen even longer.
Do more or higher value trade returns potentially shake loose by waiting another two months? I suppose it's possible. I suppose some potential Ristolainen trade partners may have prospects which truly impress and make a projected NHL roster player expendable, or another prospect redundant. But a trade for Risotlainen would still then require the trading partner to value Ristolainen more than the player sent to BUF. I think it more likely that the next 8 weeks - i.e., camp, then the start of the NHL season, we'll see a smaller trading partner market due to injuries around the league. At best, I think it's a push.
Similarly, if BUF is intent on keeping options open to give Cozens an NHL look, then the only Ristolainen trade scenario "now" which impairs that process is taking back an incremental waiver-eligible player. Trading Ristolainen for one waiver-eligible player is a push. Trading #55 for two waiver-eligible players makes it more difficult, but not impossible, to still give Cozens a cup of coffee. Teams figure out ways to do that each and every season. Minor injuries which normally would be played through can be put on IR, etc.
If the intent is to give Cozens a cup of coffee, it only "solves" the center depth for a few weeks. The longer-term need remains.
If the hope is that Cozens can fill an NHL center role for the season (which we both disagree with), then shame on Botts for making "Hope" a "Plan".
That Ristolainen is not traded "now" must be most strongly linked to either a lack of a trade partner, or lack of return value - whether that's a low return, or a low value of Risto which hopefully grows if he plays a season under Kreuger / new staff / new approach.
I think hypothetical scenarios re: Cozens camp performance don't move the needle at all on either the 2019-20 Sabres need for an NHL-caliber center, nor the return / available market for a Ristolainen trade.
