Nobody is going to "sell you" on this team, because you have already made your mind up about every member of the roster, and you automatically dismiss anything that doesn't match up with your preconceptions.
Fact is that the defensive roster upgrades are the best we've seen here since Dame was drafted, and that Dame is the healthiest he's been in half a decade, and Ant is arguably every bit the sidekick for Dame that CJ is, but a far better athlete. The biggest question marks are at the forward spots, but the talent level that Nas brings at SF (if healthy) is undeniable, and though you denigrate him, Watford looks to be shaping up as a very capable backup 4.
Quite simply, if Dame/Ant can bring the offense we expect them to, and the team can gel defensively under Billups' tutelage, this squad absolutely has a legitimate chance to make some noise this year.
