There is another problem: In "The Best of Both Worlds Part 2" on arrival at the Wolf 359 battle scene, Data reports "No active subspace fields, negligible power readings." Riker responds, "Life signs?" Data "Negative Sir."
So, apart from the unlikely event of any escape pods leaving the sensor area of the Enterprise before it arrived (the battle does look 'quite' fresh, if the Enterprise's lifepods don't have a Warp capability then why would the Saratogas', and the Enterprise can scan for light years) then -- NO ONE SURVIVED!!
Therefore, Sisko and Jake are dead -- they must have been replaced with android replicants!!
