It doesn't work that way, however, and a player that fits in well with one team may not perform so great with another team, particularly against his old team. Jason David is a case in point. Though he played well for the Colts, and is not doing too badly at New Orleans, he was brutally used and abused by Peyton Manning when the teams met this past season.
Tennessee has a talented quarterback, who has caused the Colts some problems. They should build around him, rather than try and clone the Colts by bits.
Update: Oops! I originally said David was playing for Tennessee when he actually plays for New Orleans. Nick Harper is the former Colts' cornerback at Tennessee. Nevertheless, I think the example is still valid.
