Free agency, trades and retirement loom every year for athletes, and of all the players that the New York football Giants have lost so far this offseason, five will sorely be missed.
This list is not to suggest that the Giants will regret losing the following players, but simply to rank the order in which they'll be missed.
Let's begin with No. 5.
It's doubtful that Giants fans will say in the 2013 NFL season, "If we still had Bennett, we'd be a lot better off."
Martellus Bennett clearly came to New York on a one-year deal in 2012 with something to prove, and he did.
He showed the world that he can be a starter in this league, and that he's a terrific blocker and has a good set of hands.
His 55 catches and five touchdowns won't easily be replaced by the combined efforts of Adrien Robinson, Bear Pascoe and new Giant Brandon Myers, but the hole at tight end will be filled.
Michael Boley pursuing Michael Vick.
Fans may feel the absence of Michael Boley in training camp and with the first couple signs of adversity, but he will be forgotten soon afterwards.
It's like former Giant Chris Canty told me back in early February when he was still a Giant himself: It's now or never for these young guys to step up.
Well they're not young anymore. They're not young anymore. They've got to come up and they've got to step up and they've got to play. They got to perform. You can only ride that young label out, or that potential label out for so long. You got to step up to the plate and you got to perform, and that goes for everybody on our football team. We can't rest on our laurels, we can't rest on past accomplishments. We got to have that hunger in our bellies again.
Aside from Mathias Kiwanuka's veteran presence, Jacquian Williams, Spencer Paysinger, Keith Rivers and Mark Herzlich all have legitimate chances to separate themselves from the crowded middle in 2013.
Some people are still bitter about Osi's poor 2012 campaign and aren't sad to see him go, but it's hard to argue that Umenyiora won't genuinely be missed by most.
Nine years is nine years any way you slice it, and his 75 sacks in that time will not be replaced overnight.
When Umenyiora was in his prime, nobody on that defensive line put offensive linemen on their heels like he did.
His absence will definitely be felt.
In six seasons kicking for the Giants, Lawrence Tynes kicked the G-Men into two Super Bowls.
Thirty-four years old may be young in kicker years, but the Giants just didn't want to risk re-signing the infamous right leg of Tynes.
Tynes made less than 80 percent of his field goals with the Giants in just one of his six years in New York, and that was in 2011 when he eventually helped Big Blue get to the Super Bowl and win it.
New Yorkers will never forget Tynes, but they will miss him.
New kickers Josh Brown and David Buehler have large shoes to fill.
Ahmad Bradshaw will be missed the most, period.
He was simply a gritty, hard-nosed player who possessed intangibles that the Giants can't go out and find in other players.
Bradshaw had this unparalleled will to win that really resonated with New Yorkers.
Even though he seemingly could never practice in between games because of chronic foot injuries, he always managed to be ready on Sunday to get those hard yards that the Giants counted on.
Big Blue's running game will take on a new identity now, and that's not a bad thing, but it will be strange not seeing No. 44 in the back field in 2013.
