Mailbag, part I: Will this be a career season for Alex Smith?

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: Alex Smith's career highs for yardage (3,313 in 2013) and touchdowns (23, also in 2013) aren't particularly high for a starting quarterback, so it's possible he sets a new number in each category this year. That might take a change of personality for Smith. He might have to be willing to take more chances and attempt more downfield throws than he has if he's going to get there. I don't think this is the best offensive team he's played with. The 2012 49ers had Frank Gore, Michael Crabtree, Vernon Davis and Randy Moss, albeit an aging one. That offensive line was also a good one. Smith would have set career highs that season, but he started only nine games. @adamteicher: In Maclin and Travis Kelce, the Chiefs have two very good pieces, but they're not enough. I don't see where big production will come from otherwise. The Chiefs like Albert Wilson as a No. 2 receiver and maybe he can be that other consistent threat. Maybe Da'Rick Rogers figures it out. Perhaps Chris Conley develops faster than the Chiefs initially thought he would. The Chiefs may be able to re-establish Jamaal Charles as a receiving threat. Jason Avant could have one more productive season in him. De'Anthony Thomas could have more of an impact than he did last year. But that's a lot of wishful thinking. Not all of that will work out. Maybe none of it does. That's why an injury to Maclin or Kelce would be devastating. @adamteicher: Albert Wilson is the other starting wide receiver besides Jeremy Maclin. The others getting the most snaps as wide receivers are Da'Rick Rogers, Chris Conley, Frankie Hammond Jr. and Junior Hemingway. Jason Avant is mostly a slot receiver. @adamteicher: That's impossible to say but I do know that the Chiefs had a fifth-round grade on Wilson before the 2014 draft. I also know the Chiefs are encouraged by what they saw from Wilson last year, so there's no reason to think they would have seen him as anything less than a fifth-rounder this year.
