I think the Couts, Sanheim (28), TK (27) deals are the veteran core going forward, and they probably won't be big players in FA, preferring to sign their own players long-term.
They're a very young team, and will get younger, but some will fall victim to churn.
Frost is a good example, he's had every opportunity to succeed, but has to run with it.
Drysdale is getting his shot this year, but Andrae out played him before he was hurt, we'll see if Grans is for real, McDonald will probably get a look this spring, Bonk next year and so on.
You don't have to hit on every draft pick and prospect, you have to hit big on enough of them.
