First off, I think it is a massive mistake to ever build any franchise around a PG unless he is 6'9", can play four other positions and has a first name of Magic. And yes, that includes every PG in the NBA today.
To build a franchise, my base franchise player has to have transcendent talent, size, and be able to dominate either offensively or defensively or both.
LeBron James
Kevin Durant
Dwight Howard
Anthony Davis
Kobe Bryant
Kevin Garnett
Tim Duncan
Carmelo Anthony
Dirk Nowitzki
That's it in all of today's NBA, IMHO, and I think it can be said that KG, Dirk and TD probably are not on this list next year and Davis still has to grow before he is truly that guy. Unless you have a team with one of these guys on it, I don't see your team having a chance to win it all.
