‘You know how on every incessant commercial for a lawyer or the stock market, there is the warning that “past performance is no guarantee of future results?” You should keep that in mind when it comes to NFL free agency. There are two major points to consider when mulling a contract extension for Poyer. The first is his age. At 31, he’s set to miss his second game in the first five weeks, this time because of an injury to his ribs. He also missed the Week 3 loss in Miami because of a foot injury. At 6-foot and 191 pounds, Poyer is never going to be the biggest player on the field, so his durability as he ages becomes a question. It’s understandable if the Bills don’t want to get locked into a long-term deal, given Poyer’s age.’
