Dont get me wrong, I like geno, and really would not be disappointed if we did draft him first round. On the other hand, we did just sign kolb and the 2014 draft looks promising with respect to QBs. So passing on spending a high draft pick on a QB this year isnt such a bad idea to me.
In response to your question, players I would take over Smith would include Chance Warmack, Lane Johnson, Dion Jordan, Cordarrelle Patterson, and Eric Fisher.
