I think you're missing the overall point with their non-football activities.
Title winners in England generally feature in the top 3 for wage bill spending.
That's the less spoken about other half to the 'transfer spending' discussion. Pay the big wages and attract the big stars, win silverware.
Where we are now and where we were when ENIC became owners is night and day.
In the ten seasons preceding their takeover under Sugar's ownership we averaged a 10.8 table position, or 11th essentially. That also included UCL/UEFA participation once, and that wasn't via league finish.
Under ENIC we have finished in that '11th' or below 3 times (from 24 seasons) and none since 2008. With UEFA/UCL participation in 15 of the last 17 seasons.
And yes none of that is a trophy, but it is steady and solid progress. As is developing the training facilities, and massively upgrading WHL into our magnificent stadium.
To wind back to the top to the overall point, all that is aimed at helping put Tottenham Hotspur into a position where our financial capabilities match and even outstretch our contemporaries.
That is a gap we are closing, and non-football ventures that you mock like NFL, Concerts etc are a pivotal revenue stream that is needed to achieve the end goal. Think otherwise that's fine, but without it we'd slowly drift back to the pack with the Everton and West Ham clubs of the world.
You must crawl before you can walk, unless you're Manchester City and enter a cheatcode instead.
