This is what they're talking about with the idea of a 5-tool player, and this is why ballclubs chase the dream. Other than Griffey, am not sure the M's in 35 years have had a power/speed player of Trayvon's magnitude. Check me on that.
The other power/speed guy that comes to mind is Cameron.
Cammy was a .250 hitter with 32/5/23 and a 25/7 steals rate per 162, and a .089 ISOW, .195 ISOP.
Griffey was a .285 hitter with 32/3/38 and an 11/4 steals rate per 162, and a .086 ISOW, .254 ISOP, though it was high-teens/early-20s on steals for his first decade.
I think Trayvon is more Cammy - nobody's Junior, obviously. But Trayvon's been surprisingly high with his batting average. If he's a .285 hitter for average (just taking Griffey's average instead of Cammy's) with Cammy's power he'd exceed Cammy's power slash line by quite a bit. It'd look like 36 doubles /6 3B /27 HRs just with the extra average.
That'd be scary - that's basically Carlos Beltran. I wouldn't see Trayvon as Beltran. Anything in the Cammy/Matt Kemp ouvre is just fine. Kemp has a higher average and traded a couple of doubles for HRs, both guys swipe lots of bases...
I like that just fine.
