The Facts: Following up on the ongoing story. ... The last coach in Detroit, Jim Schwartz, had a bad habit of denying that Stafford suffered from lingering on-field mechanical issues. The new guy, Jim Caldwell, knows his employment with the Lions hinges on fixing those issues and turning the team's starter into a player capable of guiding the franchise to the promised land. Asked specifically what needs correcting, Caldwell on Thursday displayed a Schwartz-like ability to steer the conversation elsewhere. "He's hungry to improve, I've noticed that about him. He's eager. He's a willing worker, he's smart and he has tools," said Caldwell, adding that "a lot of people want to talk about so many other things that really aren't that important -- whether or not he's elite, or this or that -- that doesn't matter. We want a championship quarterback. ... And I think we have the makings of that."

Diehards Line: As NFL.com's Marc Sessler suggests, Caldwell has a recent reference point after guiding a decidedly sub-elite passer in Joe Flacco to a Super Bowl title two seasons ago. Like Stafford, the Ravens quarterback is flush with his own on-field quirks, but -- also like Stafford -- owns one of the league's strongest arms and all the tools you'd look for in a franchise passer. The issue with Stafford has been less about his potential and more about fine-tuning his deep pool of physical gifts. Meanwhile, Caldwell assured that Lions fans will "see Matthew take the bull by the horns and do all the little things that are necessary to get us to keep moving forward as a team. ..." We'll see.
