I'll state it one more time then leave it at that, Madden 2006 for PS3/360 was an admitted bungling, much like the handling of NBA Elite. Both set out to develop something that they realized wouldn't pan out prior to release but Madden was still able to salvage a releasable game, in an exclusive market, whereas NBA Elite would have been released in a directly competitive market. It begs to reason that if the NBA Elite demo had been released in a scenario where EA had a NBA exclusive license, they would have salvaged what they could for a release, like they did with Madden 2006.
Ergo, a clear example of a moment a poor quality Madden was likely able to avoid a NBA Elite style cancellation due to the exclusive license.
