I have a hard time believing the locker room is happy that Vinatieri isn't being held accountable the way others have when they haven't performed.
If I were a player who got benched for poor play, or even cut, I'd be very upset that Adam keeps getting chance after chance when he is killing this team.
I don't prefer to trade high picks for players. I don't know how GMs project guys who transfer teams. FA, trades, there's enough examples of guys who have migrated to a new team and have been a massive failure. The opposite of course is true (bust turned quality starter). What I'm excluding from this conversation are the guys you swap with teams for low grade picks or similarly rated guys you bring in expecting to be nothing but a backup or S/T. They can blow up of course, and that's great. But I am not counting those as part of this analysis, because what the question was related specifically to "building" a team, which I take to mean core players.
Because the spectrum of results is just so unpredictable, I really only like it when it's a Day 1 or 2 player still on his rookie deal that we can get with little investment (Eli Apple, for instance). Even then, I'd like to get the guy for more than just a year (as opposed to one season or less). I definitely don't like trading for marquee players on their second contract.
That is the general rule. HOWEVER, there are a few players that I'd pay for, whether it's multiple high picks, or a player with a top tier contract. For instance, there was a point in time I'd have given multiple firsts for JJ Watt or Von Miller. When Khalil Mack was available, I wanted him pretty bad. If a guy like Pat Mahomes was available today for trade, I'd strongly consider it (what price would that be!? oye!). Guys who are cornerstone players, especially guys who are cornerstone players still on their rookie deal, the general rule doesn't always apply. I know the trade value is tough to swallow, but as long as it doesn't keep you in perpetual purgatory, you can survive it if it's the right player.
There's a limit of course. While I follow the general rule 99.9% of the time, there's always that 0.1% of players in the NFL that I'd pay an arm and a leg for.
