Let us presume that there are perhaps 7 players available who are about equal and who might be draft in the top 10.
========
Should we simply take our choice of the bunch, knowing that we could get about the same quality player a few spots later?
In this situation, it seems right to trade down a bit, even if it is for only one additional pick.
To be clear, if we have 3 players equal when draft, why not trade down two spots and add a pick.

Obviously, if we have someone clearly higher than the rest, then we would pick that player.
