Reed ans Sepulveda are the least of the Steelers' worries this off season. I would love for Reed to stay, the same for Sepulveda, but not at a price above market value for either. Sepulveda is middle of the pack, except in downing the ball inside the 20, so you give him a little premium for that and make him an offer.
Reed is clutch on fields goals in any stadium and deserves fair market value for his services. Inside 50, he's money and 50 plus not so much, his KOs leave a lot to be desired and so, a reasonable offer should do the trick. If someone is willing to pay him over the top then let him walk. One's a kicker and one's a punter they play about 7-8 plays per game. There are guys out there that can replace them.
