I don't think he has ever been regarded as the main player. When I say "build around", I am thinking about a core of several players (like Whitaker, Trammell, Parrish, Lemon, Gibson, Morris). So far, he is petty far from that class of player. It's still possible he could reach that level, but progress has been slow and he doesn't really have a position. He seems more like Johnny Grubb than a building block. And that's not a knock against Grubb. Grubb had a pretty good career as a role player. I am talking about his entire career, not just his years with the Tigers.
