If they're just starting out (1st VP's) I'd do each of them with Second Wind first. You can always swap it out later and Stamina is the #1 issue with lower level dots.
I'm just gonna list the top 3 (IMO) because they're likely the one's you'll get the most agreement about. After that, it becomes more 'build specific' and also the supporters/detractors get more diverse depending on their viewpoints.
Speed WR; Sure Hands / Slippery / Mr. Reliable (Arguments can be made for Possession Receiver but it's limited to short range passes... for Slot Machine but requires ONLY playing the #3 WR position... Nerves Of Steel but it's a much better VA for Possession arches... Clutch [pros and cons]... Quick Feet).
Receiving TE (and depends on the style of build since a Rec TE can be either a Possession type or a Speed type); Possession Receiver / Sure Hands / Mr. Reliable or Nerves Of Steel (Ball Hawk is good... Clutch is good... Yac Attack for a Possession type... Slippery for a Speed type... many of the WR VA's above).
EHB; Slippery / Quick Feet / Track Star (While some might poo-poo Mr. Reliable, consider this... on 1st and second down it gives you a 5% bonus PER LEVEL to avoiding fumbles... and, as a EHB, most of your quality carries will be on 1st and second downs... Punishing Runner [drains opponent's energy]... Clutch).
Possession WR; Pretty much the exact same as Receiving TE above.
Cover LB; Sure Tackler / Long Reach / 3rd Down Stopper (Others of note; Ball Hawk [make sure you'll be in Zone Coverage before getting this one]... Clutch)
And, for all of these add this on to each. Be sure to check your ending 'skill #'s and see if you have any that need a little help... or any that are highly important to the archetype/position. Example... the EHB could use more speed so you get Track Star... the LB could use extra vision so you get Football Genius... or the TE could use some extra catching help or jumping help... there's Soft Hands or High Jumper. In other words, you can't go wrong with getting extra bonus help to your skills when you're at a loss for those last few VA choices.
And, last of all... this one is one of my favorite tricks for many of my dots. When you're at the end of the VA building, you generally end up with around 12 VP's left over to put into one last VA. Make it Overtime Killer (OTK) and put all 12 in if you DO go that route because you not only get the end of the 4th quarter bonuses in close games... but each point in OTK adds 20 seconds MORE onto the time it works in the 4th Quarter... so 12 points means it'll start kicking in with 4 minutes remaining and last until either the end of the game... or until the end of Overtime. VERY important for QB's, IMO.
