Shortstacked Button Pushes My Bb

[Hoop Addict 0]

Final 5 of a $7 rebuy. 3K starting chips + 3k rebuys means there's a little more play in the FT than usual.Blinds are 5K/10K, no antes. I'm in the BB with 445K after posting (chips leader - next is ~360K). Shortie is on the button with 65K. He's been a shortie for a while & doesn't seem in any hurry to get his chips in. In fact, he folded to min-raises in his blinds.It folds to him on the button & he shoves. His range can't be too loose, IMO, since he's been patient while being the shortie. Everyone else has over 150K.The SB folds. What do I need to call? Should I be calling with basically ATC? Short my range be more like any PP, A10+, KJ+ & maybe some suited connectors? This is a situation I've been in before, but have never really known what my range *should* be here.
