Quoting: aedoran
The only problem Detroit has no interest in Risto.
First, great analysis, and this is way too much for Ristolainen. Neither Girgensons (BTW please check out his possession stats, they are off the chart, 50% corsi for with only 15% OZ starts) nor Smith add much on the Sabres side of the ledger while Mastrosimone is a big asset. So even if one were to start with the assessment that Mantha and Ristolainen are close, the additions heavily tilt the scale in favor of Buffalo.
Second, I have seen the Eklund tweet regurgitated a couple of times a week, while I am not that familiar with his predictions, as you said, his post is the only source of this rumor.
Third, the reports of Ristolainen wanting out can also be traced to a single interview when he said he was unhappy that he could not lead the Sabres to the play offs, not that he was unhappy in Buffalo, nor the Sabres.
Fourth, as a Sabres fan, I would only trade Ristolainen unless a player with a similar upside as Mantha was included. I could be in error but big players take longer to develop and defensemen take even longer. Many current star NHL defensemen finally put it together just about the same age as Rasmus.
Fifth, I do not know the value of Ristolainen, it may be Mantha, it may be less, it may be more. Regardless of what we as casual observers believe it is a fair trade, it is the GM’s who decide fairness (i.e. Subban, and Skinner trades are good examples). So I would rather keep him, play him fewer minutes, give him more OZ starts, and put him in situations where he could excel.
Finally, I do not think Buffalo and Detroit are good trading partners. I can see Mantha bringing the Sabres closer to the playoffs; does Ristolainen do the same for Detroit? The teams tied with 76 pts last year, IMO Buffalo is a top RW, a 2nd line center and improved GK from being competitive. Mantha fill the first, a bulk up Mittelstadt could fill the second and Bales coaching may do the third.
