Because those 2 guys, plus the 2 mil in salary relief, was in all likelihood the best possible value we could get for Kevin. The potential benefits that the guys we got and the stability created by the moving of youk outweigh, in my opinion, the chances of Kevin making us regret this trade.
It's that simple. Give it some time. Lillibridge is a decent utility man and maybe Stewart can figure himself out and get some velocity back on his heater. Kid was a big deal not too long ago. He's still just 25.
