The addition of veteran signal-caller Sam Darnold might complicate things, however, but a healthy competition in camp could be exactly what Lance needs to re-establish himself as the team's starter.
And, in Martz's eyes, there's no ruling that out.
"I just think he needs to be in longer," Martz said. "I think it's unfair to him, at this point, to say that he can't play -- but he's a long ways away. ...
"If he stays [in San Francisco] or wherever he goes, he's got to up the ante a little bit in terms of, you've got to be more invested in trying to learn what's going on out here."
ppl in their minds interpreted it as he's a bust take, that's not what the man said or is saying, it's a he needs a lot of work take; he has offseason tho and what is offseason for? other than work / improvement..
