Not if it's the right guy. CC who came up at 20, hit FA in his 20's, been a top tier performer most of the time, gets Ks, limits base runners, possesses elite size, a top tier fastball from the left side, and two other pitches he can get K's with? Yep. Carlos Beltran hitting FA at 27 or whatever it was? Batting average, contact, elite base stealer, strong CF defense, good arm, stepped up in bigger scenes, not walk adverse, and so on? Hells yeah (still IMO a mistake to not chase him). A guy who's been injured, pops up for a couple of strong years, doesn't possess any top tier attributes otherwise or has major, obvious holes? Nope. Context...learn to apply it because it's everything in team building and FA. Sometimes it works and sometimes it doesn't, but knowing as much as you can and finding value in it improves your odds. Cole Hamels, IMO, has the kind of combo of health, pedigree, skill, talent, and performance that lessens the fear. You're going to take the dive at some point....
