You're hoping for .290/.360/.450 or thereabouts, IMO. His home run power, from what I've noticed, all comes from the same spot. If you throw it down and in he will golf the ball out of the park. Just look at a highlight reel from him - it's all from EXACTLY the same spot. If that power is enough to golf it out to LF in Safeco, all well and good. If it dies out there like it did for Beltre, then you're in trouble. Gar was successful because he hit with power to all fields. Not necessarily HR power, but power. He would pepper the opposite field wall. I'm not sure that White has that same skill.
Of course, White is 34.8 times faster than Edgar and can leg out a few more doubles to make up for it. But you're really looking for 40 doubles and 15 homers. Again, the Mark Grace profile (which was really 37 and 12 per 162 but who's counting). Of course, Grace was a lefty and had an eye way more like Pavin than White. Trying to think of a light-hitting righty 1B with that template. Gimme a minute. ;)
