I watched T-Mac for years as an Orlando resisdent, and I've seen plenty of Suns games as well. I'm going to have to side with taking T-Mac over Marion.
Marion is a great piece to the puzzle and fits perfectly in the Suns system, but I think T-Mac could score 27 a game on almost any team.
When T-Mac is on fire, there is no stopping him.
I remember one Magic game 2 years ago, where on 4 consecutive possessions, T-Mac just walked the ball up the court, and immediately popped a long distance 3 right in his defenders eye. The defender was completely helpless - basically it's just T-Mac missing a shot if he does, and it had little to do with the defender.
And it's hard to forget the Rockets game this year where he scored what - 12 points in the last 40 seconds or so?
That ability is extremely hard to find. If he actually busted his ass on defense, T-Mac has all the talent to be a NBA 1st team defender too. Maybe someday he will get that serious.
Marion has pushed his talents to the max but I think he will fade more quickly as his athleticism declines. He isn't a go-to guy, he prefers being
the 3rd or 4th option - staying out of the limelight, just hustling, and
filling up the box score with rebounds, put-backs, steals and blocks.
A great player to have on your team, but I just feel those attributes can
be had more easily than an unstoppable scorer who can get to the FT line
at the end of a game, or make the huge shot.
As far as the MVP for Nash, I have to disagree. I feel it should go to
Shaq who has (absurdly) only won a single MVP. He went to a team with
Wade, a 2nd year player, and a bunch of scrubs and took them to 2nd best
record in the league, and 1 seed in the East. He makes everyone else better just as much as Nash, and he's a go-to guy and dominant on both
ends of the floor at times.
