I think you have take Need off that list, because I don't think you want Need effecting your evaluation for 'best player'. The analysis of Best Player has to be objective, and determining Need has to be objective of what's available. He's either the best available, or your biggest need. SOMETIMES those overlap on the venn diagram, but the two need to be evaluated separately. Then you determine your draft strategy, and that's when need becomes a factor in the choice.
That all said, when you're picking top 10, I think you have to take the best player on the board. Outside of a couple factors, like you're not taking a QB, or LT, this year, but with so many different position groups cycling so many players throughout the course of a game, the best player who can be a day 1 impact at ANY position is how you continue to layer the best talent. It's how the best teams seem to always get the best players, because they dont give a damn what position they play, they want the biggest impact.
This year is an even bigger testament with Jeremiah Love. He appears to be the kind of guy that changes everything, not just the RB room. There are only a handful of players in the league right now that can effect that change like that. I like Tate, Tyson, and Styles, but does Love have the ability to be one of the 3 - 4 best players at his position? Does Tate, Tyson, or Styles have that ability? That's where the true debate comes in when you're figuring out who to put on the card.
As the draft goes on, and the talent level balances out a fair amount, the need factor becomes a much bigger part of the decision making, but when we're talking about the top talent, unless there is a massive need at a premium position, you dont pass on the better talent.
