If you had your way running a football organization, nobody would want to be a part of it. Strictly incentive laden deals may deter a veteran player that has produced year after year, from joining your organization. Guaranteed contracts should be be a part of football. However, I think any deal longer than 4 years isn't good for business. For example, the deal for Kirk Cousins is ideal, because it coincides with the Vikings' perception of their championship window. He gets paid for his service as a franchise QB, and if the Vikings aren't satisfied, the contract has ended with all money paid out.
Obviously, one year deals are not an ideal way to construct a roster, however they are important in "hedging your bets". Because essentially that's what a draft pick is, a bet that a player will live up to potential. I proposed on year deals, and I think I was quite clear, as a means to maintain production from an experienced player, either due to injury or the unknown expectations of a rookie. Roster construction is a fluid process and should remain so. Sticking to a basic template can sink an organization.
Definitely not a Patriots fan, but I like their business model. They target players they cannot live without, pay them, and fill out the rest of their roster with mid level players and draft picks. Players they have drafted, that exceed expectations, but do not fit the roster construction are flipped for other teams's draft picks or once that player leaves the Patriots are rewarded with a compensatory pick. Either way they replenish their roster without allocating money for a player that doesn't fit their vision of the roster construction.
