I dont really go into any draft with a set, I am going to do this or that. You never know who may fall to you in leagues. I do have a preference for drafting later in the round though. Reasons for this are,
1. Someone might fall and you are there waiting on them.
2. You get a better second round pick than the earlier round guys.
3. It is easier to work out who might be taken after you based on how teams are looking in later rounds, with less picks between yours.
I seem to nail my second pick on a regular basis drafting late in the 1st round. So in a 10 team league I would like to draft in 8 - 10, 7th at the earliest.
