Mailbag, part I: Will Chiefs invest in a new QB soon?

KANSAS CITY, Mo. -- Here is part I of this week's Kansas City Chiefs mailbag. Look for part II on Sunday. To ask a question for a future edition, send it to me via Twitter (@adamteicher) and tag it #ChiefsMail.

@adamteicher: This season will go a long way toward the Chiefs' long-term picture at quarterback. If Alex Smith has a big season, I can see him being their quarterback for a lot of years. He's only 31 so age won't be an issue for him any time soon. But I could see the Chiefs getting restless about him if he doesn't respond with a big season. They spent a lot of money on wide receiver Jeremy Maclin and have one of the NFL's best receiving tight ends in Travis Kelce. But the problem would be in finding a replacement. It's just not that easy.

@adamteicher: At this point of his career, Jamaal Charles is who he is. I would think if he was going to solve the problem, it would be done by now. But I do think he's better than he was early in his career with regard to holding on to the ball.

@adamteicher: Marcus Cooper has a much better chance now than he did before Sean Smith's suspension. I don't see the Chiefs keeping any less than five cornerbacks and now I see Cooper joining the list that includes Phillip Gaines, Jamell Fleming, Marcus Peters and Steven Nelson. Somebody probably goes when Smith returns, though, and Cooper would be the most likely.

@adamteicher: There is none. Dontari Poe plays an extraordinarily high percentage of the snaps for a 346-pounder. I'm interested in looking at the Chiefs' sixth-round pick, Rakeem Nunez-Roches, at training camp. Maybe he can hold up for a few snaps every game to provide Poe rest.

@adamteicher: Great idea but don't count on it.
