He might swing a deal — he might not. Who are you shipping out, and what price do you really want to pay for a rental that is gone after 20 games plus what ever you manage in the playoffs... or are you resigning him???
I believe if he wants to see his team reach the next level, yes, additional help on the wing is needed.
There is a role that certain players play. While Kuhnhackl, Leo, MDC and Martin (per an earlier post) may not be all stars, they play a role — particularly Matt Martin. This team is not the same with Martin, Cluttebuck and Cizikas don't play together. It is just not. They are the glue to the forwards. I know that is odd because they make up a 4th line, but they do what a 4th line is supposed to do — create energy, wreak havoc, and piss the other team off. Plus — in this case, they allow the other 3 lines to set nicely for Trotz.
The others mentioned — sure, they could be part of a trade, but none of them are getting you the scoring forward we need. Perhaps one of them with a 1st round pick in 2020 plus a prospect will land you what you need — but that is a steep price.
I wonder if before making a trade, Bellows is given a shot to see if he can add a spark. I think Wahlstrom should spend the balance of the season in BP barring an injury. Let him develop his game in peace. Bellows may have found a little something with that kick in the pants. Failing Bellows sticking, then I think you make a deal (maybe one involving Bellows, one of the aforementioned roster players — and a lower pick (3rd round) and that would be alright for a rental. Unless we are getting a serious impact player, Id like to keep the first. I think you only trade the first if it is a bigtime player who can push you over the hump to at minimum the cup final; ideally a cup.
