I just don't think Pierce has the well-spoken nature and personality for broadcasting. Love him, I just don't see him being successful at the gig. I feel like he's too moody.
As for not getting a gig because he's not a star - what? Guys like Jalen Rose and Jamal Mashburn and Jon Barry got right into the national scene so being a star is clearly not a prerequisite. I think his personality will inhibit him more than anything else, but his "star" power won't keep him out of the national scene. I recognize that he doesn't have the same "star" quality as Barkley or even Webber (even though he had a far superior career to Webber), but to lump him in with Donny Marshall as opposed to Rose or Mashburn or Barry?
As for McHale, if he wants to do broadcasting, he'll be national. I think it's a well known fact in NBA circles that McHale is one of the absolute best personalities in the last couple of decades of the NBA, right up there with Barkley but without as much foot-in-the-mouth. He won't replace Tommy - he'll replace Walton on ABC/ESPN if he wants. He'd be their Barkley type guy who will just rip into people in a hilarious way.
I agree with Grover, nobody will ever equal Tommy because there's nobody who has that lifelong dedication to one championship organization. McHale would be an outstanding color man for the team, but he's got too much invested into Minnesota as well. Tommy works so well because he is completely Boston, McHale, as great as he is, could never just be Boston.
And LA, I would love to see him doing TNT games if only for the back and forth he and Barkley could have pre-game, post-game and at halftimes. Plus his occasional studio visits would be great TV.
