One thing I’ve always struggled to factor in is players aging. Early in a career, you hope that a player will see jumps in their play relative to prior season (a guy like Rousseau). At the other end of the spectrum, it’s not unreasonable to assume that other guys’ performance starts to trail off due to age and injury (Morse, Diggs, Miller, Poyer, Hyde, White, etc.). I’m definitely optimistic about the off-season moves, but one can’t just assume that all returnees will be able to play at the same level as last season as well.
