"Probably"
Scotty has never said, "I can,__________", you pick the subject. A good scuff doesn't do it like that. He might say, "I might be able to,___________", again, you pick the subject.
If a discussion or argument incurs he will push the subject. If not he might try another, “Or I might even be able to,_______________”. Knowing all the time he can do what ever he says. The good scuff makes you think he is not sure if he can do the feat. Obviously, if he can do a shot in 5 attempts he will ask for 30 and negotiate down.
Sonny Springer was the master of getting out with the money while the guys were still scratching their heads. Never a clue who just snapped them off. Scotty wants you to know who he is. When he says, "I probably can,_______________", yes, believe it.
