Panarin, Zib etc can and like to shoot the puck. So do Laf and Kakko. Kreider has a pretty handy wrister, Buch scores a few, as does Strome. Chytil likes to shoot. Otherwise, trade for Laine
I'm more interested in having a strong cycle game, a couple of strong two-way centers behind Zib, better overall structure and zone exits/entries etc. Scoring/shooting is the least of this teams problems. Tampa, Colorado, Florida, Toronto, Carolina, Winnipeg etc hardly play a prototypical shoot first game. Even Boston's first line doesn't. Montreal do, but their offense sucks unsurprisingly. The good teams don't play that kind of hockey anymore.
I checked the Blues forum - apparently Thomas has been checked out since the bubble last year. They do talk about his high upside but something is not right there. Maybe a change of scenery is what's needed. Could be a case of buy low for high reward, I wouldn't overpay for him though.
