Do we know who Hes looking at
Quick answer? No. But we can try to deduce.
Rochester has a 6-3 record, but Buffalo is atrocious, so it could be players on that team as Buffalo looks for help. Thing is, it's hard to imagine Tallon being too interested in anyone on that team except McNabb or Varone, and harder still to imagine it's Varone, whereas I don't see Buffalo wanting to move McNabb right now. Also have to keep in mind both are older than most prospects and still playing in the AHL (Varone doesn't appear to have been drafted, signed with them last year), and neither have been called up despite Buffalo isn't doing well. But then again maybe Tallon's there to see if he can see something in them Buffalo's scouts don't.
Buffalo also fired their coach and rehired Ted Nolan today, so who knows if they're making moves just yet.
Hamilton has a sub-.500 record right now and Montreal has a similar record (just below .500). They're also out of the playoff picture early on but really close. They could be looking to make a move to help out. So Hamilton has a number of players not good enough for Montreal but could be good enough for the Panthers. Whom exactly Tallon would be scouting is anyone's guess. Panthers need help on offense, defense, and possibly goaltending.
