You know all this talk about Spencer reminds me of another 1st round draft pick by the Tigers who was much heralded as the greatest thing since sliced bread coming out of college. He too made his debut at age 22, and struggled mightily his first 3 years in the majors. More so than Spencer, and it can be argued he was a worse defender than Tork. That player went on to a 17-year career, 2 WS championships, and an MVP award. That of course was Kirk Gibson.
I think everyone one of us would be thrilled if Spencer had that career. Or even the career of Bob Horner. Point is that not everyone, and maybe only a couple of people a generation come up and play like gangbusters and keep it up for their entire career. He is still figuring things out, and there will good and bad days. Way too early to write him off.
