No one will ever admit to this, but roster decisions are a guessing game sometimes. The Philadelphia Eagles are evidence of that. Just take the draft picks they’ve made and the free agents they’ve signed over the past ten seasons. No one knows how these things work out.
Sometimes, you have buyers remorse immediately, Mike Wallace and Torrey Smith for example. Sometimes, it’s a bad scheme fit. At other times, it appears guys aren’t over injuries or they’re aging. At still other times, the dreaded salary cap won’t let you keep too many good players.
