4. Who’s in on Jacob Trouba? As best as I can tell, the list includes Arizona, Buffalo, Boston, Colorado, Detroit and the Rangers. This is purely a guess, but I could see Dallas and Tampa lurking. No idea how the Lightning could do it but Stars GM Jim Nill is always looking to upgrade his blue line. I’d thought Montreal but a couple of sources doubted it. Florida was trying before the draft but its moves afterward likely eliminate the possibility. The asks have been high. It wouldn’t surprise me, for example, if the Jets asked Buffalo for Rasmus Ristolainen, a right-hand shot who has played the left side. Apparently, some of those teams have been told they don’t have enough, which has led to them trying to involve third parties.
