The Edmonton Oilers have had the kind of July the organization badly needed. A reset in net and two new left-handed defencemen, plus a pile of cap room and increased roster balance; the mood among Oilers fans is upbeat.General manager Stan Bowman could go to training camp with the current roster, satisfied that last season’s holes have been filled with legit solutions. However, since there’s time and money, it’s good to look around and see what might still be available for trade. Bowman has some waiver-eligible talent that he could deal before camp (specifically defenceman Spencer Stastney) in an effort to improve depth in other areas.Here’s a list of productive prospects who could be acquired this summer, for cap room, Stastney, draft picks or any combination of pieces.Matt Poitras, Boston BruinsThere was a time not so long ago that Boston Bruins centre Matt Poitras looked like he was something special. He was an impressive NHL rookie in 2023-24. Just 19, he posted 5-10-15 in 33 games with the Bruins. At five-on-five, he delivered 2.00 points per 60, a 57 percent goal share (54 percent expected) and played well in an area of sudden need for Boston. The club had lost two foundation pieces at centre (Patrice Bergeron, David Krejci), and Poitras was one of the young players who stepped into the breach and thrived.There were concerns, though. His foot speed was less than 50 percent, and he was playing mostly sheltered minutes with veterans like Morgan Geekie, Jake DeBrusk, Danton Heinen and Trent Frederic. The coaching staff faded him heavily against elites (as you would with a teenage centre) and his results against mid- and lower-level competition were splendid, via Puck IQ. The audition lasted 33 games, but most observers looked past the speed issues and the faceoff percentage (44) and admired the gigantic leap from junior hockey to the NHL. There may have been a rush to connect Poitras to Bergeron, who did, in fact, leap from the QMJHL to the NHL and arrived fully formed 20 years earlier.The story for Poitras has turned out differently. His second pro season was split between the NHL and AHL. There were good scoring results in both leagues, but the goal share plummeted with Boston, and it was clear Poitras was going to take a longer route to becoming an NHL regular.
