Just some things to consider about Ichiro:
1. Because he leads off, never gets hurt, and swings at everything, Ichiro ends up with an ungodly # of ABs each year. This means that his BA counts more heavily in determining your team average. Ichiro hitting .310 over 650 ABs is likely to help your BA more than Manny Ramirez hitting .320 over 500 ABs.
2. His power numbers aren't awful - 13 HR and 62 RBI last year. He's not a totally punchless Juan Pierre or Alex Sanchez type.
3. Ichiro was 9th in the league in steals last year, and tied for 11th in runs scored. He's not just solid in those cats, he's among the very best.
4. Ichiro's 2001 was simply amazing. He led the MLB in BA and SB and was first round value that year. It wasn't that long ago so some people are going to draft hoping he can put together another one like it.
