Tons of talent that transfers after middle school to Mooney/Ursuline. No secret the Spartans best seasons are when those programs are having “down” years.
I respectfully submit that the highlighted statement is debatable. If one considers making the playoffs as a "best season" then Boardman has qualified for the playoffs 12 times and if one were to look at Mooney's record in those same 12 seasons one would see that for the most part the Cardinals also had successful seasons.
Boardman qualified for the playoffs in 1987, 1990, 95, 99, 2001, 07, 09, 11, 15, 17, 18 & 2020. Mooney qualified in 9 of those seasons, played for a state championship in 4 of them and won 3 state championships in those same 12 seasons. The Spartans best season in terms of playoff success was 1987 when they finished as D1 runner-up.
The following are Mooney's records in Boardman's playoff seasons.
1987 - Mooney finished 12-1 D3 state champion
1990 - Mooney finished 11-2, lost in D3 semis
1995 - Mooney finished 10-2, lost in D4 regional final
1999 - Mooney finished 12-2 lost in D4 semis
2001 - Mooney finished winless (I count the Ursuline forfeit as a loss)
2007 - Mooney finished 14-1, D4 runner-up
2009 - Mooney finished 15-0 D3 state champion
2011 - Mooney finished 11-3 D3 state champion
2015 - Mooney finished 4-5 (Boardman finished 6-5)
2017 - Mooney finished 7-5, (lost to eventual state champion Big Red in 2nd round of D4 playoffs, 19-14) (Boardman finished 6-5)
2018 - Mooney finished 4-6 (Boardman finished 6-5)
2020 - Mooney finished 2-6, lost in 2nd round (Boardman finished 4-4)
I don't think the 2015, 17, 18 & 2020 seasons can be considered among Boardman's best but they were playoff seasons for them.
In addition I personally consider the 1985 & 86 Boardman teams to be among their best even though the Spartans did not qualify with 9-1 and 8-2 records respectively. Mooney qualified both of those years and finished as the D2 runner-up in 1985 with an 11-2 record.
Also, I believe the vast majority of kids from Boardman that attended Mooney over the years were from St. Charles not Boardman public schools.
