Tuesday, in an Insider piece, ESPN.com looked at the biggest question every NFL team is facing in the offseason. Here are the three biggest questions facing the San Francisco 49ers in my opinion:1. New deals: The 49ers have several key cogs to lock up. The most pressing are quarterbacks Colin Kaepernick and coach Jim Harbaugh. Kaepernick has one year remaining on his deal and Harbaugh has two years. Neither deal absolutely has to get done this year, but it would be a lot smoother for everyone involved if there was some clarity this year.
