Hawpe is 32 and hasn't played in anything approaching a full season since 2009.
Raburn is also around 32, has NEVER played a full season, as overall bad to mediocre (at best) 162-game numbers. Awful OBP, little power, no speed.
Are they an upgrade? Maybe (assuming either of them is capable of playing a full season). But you really want them? Getting them would make you happy?
