Outside linebacker Aldon Smith is one of just 12 players from the first round of the 2011 draft class who has yet to have his fifth-year option exercised.

Smith, the 49ers’ selection at No. 7 overall, is by far the most accomplished player in that group of players. Smith's off-field issues are the only reasons the 49ers have not already made the decision public.

Smith is clearly the one who does not belong in a group of players who have not had their fifth-year options exercised. The list includes:

--Three players who are not eligible for fifth-year options because they are longer with the teams that drafted them and are on different contracts. San Francisco 49ers wide receiver Jon Baldwin falls into this category. The 49ers traded for Baldwin last summer but he accepted a dramatic pay cut in February to remain with the 49ers in the offseason. Offensive linemen Danny Watkins and Gabe Carimi are also ineligible for the fifth-year option.

--Three quarterbacks who have not proven to be starting caliber. That includes 49ers backup Blaine Gabbert, whom the 49ers acquired in a trade with the Jacksonville Jaguars, as well as Jake Locker and Christian Ponder.

--And five players who simply have not produced up to expectations, for various reasons: Nick Fairley, Adrian Clayborn, James Carpenter, Mark Ingram and Derek Sherrod.
