I think MacTs thought process is to see if anyone of Arco, Lander, Draisaitl or the wild card Yakimov can step up grab the middle six center positions, if only one of the four cuts it, they'll use Gordon as the #3 and Hendricks as #4 and hope we can stay afloat long enough to find a trade that makes sense.
I also think they're hoping that if the young centers above can't keep up at least two of Marincin, Klefbom, Nurse or even wild cards Simpson and Aulie shows enough for us to move Petry in a package for a center, Berglund who might get caught in a numbers game once the season starts for example. So basically the bet is that three out of our group of promising young Cs and Ds can look like real NHLers.
Also they probably hope RNH can take a step and become a somewhat adequate #1 C this year. Giving the rest of the Cs some actual insulation.
A lot of gambles but they make some sense and since we're nowhere near contention I don't mind it. I don't really see the point of going after so so centers on the decline just to fill a void, I think there's a point in seeing if the young guys can step up to the plate, Lander has mastered the AHL, Arcobello did look ok to start last season and tore it up when he returned to the AHL, Draisaitl is an elite prospect, Yakimov was a solid KHL player at 19 and has extreme size that might let him contritbute earlier than expected though an early NHL entrance might not be the best way to maximze his potential. It's not out of the question that we'll get enough out of them to stay somewhat competitive until Draisaitl is good enough to carry the load.
Us Oiler fans are sick of staying patient but our chances to eventually contend lives and dies with development from within. At this time I think we need to bet on this guys instead of giving up assets for doubtful solutions to a key position. If the team starts the season looking terrible again then I'd understand some desperation looking for trades and short term solutions as another disaster of a season might kill all confidence, joy and sense of winning of our young core. If the team however looks like they're taking a step in the right direction, which I think they will, new #2C or not, I'm perfectly happy with that.
