Why stop there?
Since they were well before my time, take 5 from the Sox and 3 from the Bruins. I’d give up all six Pats titles, haha, but let’s leave them two.
29 titles would sound good. It puts us two ahead of the Yankees.
Take 5 away from the Red Sox and there will be mass suicides in the Boston area. The Sox fanaticism is only paralleled by Eagle's fan down in Philly. So for the Sox, I say, give 'em all the titles they need, as a matter of public health.
And the Bruins, well, we do need Orr, Esposito, and company to have their days in the sun.
As for Brady/Belichek, they have the longest lasting dynasty of all time. I mean seriously, even the Russellian era only lasted 13 years. These Pats will last past 20, setting all time NFL records in the process.
I recommend giving the 1st win over the Eagles to Philly, so that we can travel safely in that region, circa 2004-2017, without being assaulted by a nutjob if any of us were wearing any Boston attire.
And then, keep the Butler interception of 2015 so that Pat's fans have their 'Havlicek Steals the Ball' moment. So we simply then, drop the SB against the Falcons. And then, we win this SB, and we're at 4. That would give us 4 wins and a 20 year run in the playoffs, not bad for any football team.
