If we were talking about the 2019-20 QMJHL season then I would be more inclined to agree. This is when I believe the two became regular linemates. Consider the following:
XB D-2: 65GP 7.339G 13.629A 20.968P
XB D-1: 65GP 34.048G 39.206A 73.254P
XB D0: 65GP 44.828G 44.828A 89.656P
XB D+1: 65GP 54.418G 58.953A 113.317P
MB D-1: 65GP 25.390G 29.453A 54.843P
MB D0: 65GP 38.469G 55.714A 94.183P
MB D+1: 65GP 44.107G 55.714A 99.821P
MB D+2: 65GP 41.935G 100.645A 142.580P
Bourgault does see a massive jump in his numbers from his 16 year-old season to his 17 year-old season (keep in mind Bourque is virtually a year older) but I want to point out how much steadier the growth in Bourgault's D-1 to D+1 seasons are compared to the two stagnant years of Bourque's before we see a massive spike this season. Mavrik's goal scoring doesn't change much from the year he was drafted through his final years of junior but we see a literal doubling of his assists in D+2. This could very easily be explained by just the physical maturation of whoever is scoring the goals for that line (Bourgault) as his improved ability, size, and speed is making him more available to benefit from Bourque's high passing skills.
ON D-1: 65GP 16.810G 8.966A 25.776P
ON D0: 65GP 24.853G 61.176A 86.029P
ON D+1: 65GP 35.000G 43.000A 78.000P
Consider the third piece of the puzzle: Olivier Nadeau sees a similar spike when he and Bourgault are moved up with Bourque in 2019-20. Note however, the massive jump in assists with only a 25% uptick in Bourque's goal scoring. Meanwhile, Bourgault's goal scoring almost quadruples before he builds upon that production with his development. Nadeau's production tails off this season as both Mavrik and Xavier lost considerable time due to injury. I think Nadeau has very much been a passenger to the superduo that Shawinigan has been very fortunate to watch over the past two seasons and his D+2 and transition to the AHL will be very telling in what the Sabres actually have in him. I don't see much more than a 4th-line checking winger in Nadeau personally.
Bourque is a phenomenal prospect and has probably overstayed his welcome in the QMJHL by a year and a half. Damn shame the Stars couldn't get him playing in Texas during the Covid exception. However, the production of this line very strongly suggests that Xavier is the straw that stirs the drink. Mavrik's play didn't begin to elevate until he had Bourgault as a mainstay and I don't think he'd have reached so far up the upper-echelon of CHL production numbers without a linemate that could outscore him.
I think the transition from QMJHL to AHL will be very telling for both of the top Shawinigan prospects: even-strength goal scoring is the most important stat to consider when looking at the translation from one level to the next. Playmaking is important but unless Mavrik dedicates more time to developing his shot to beat ever-improving netminders, he'll peak as a poor man's second-line center.
