Like should I go strictly for an RBI guy now, or try to increase my lead in average, or go for homers, or what?

Just to be redundant here....

You said average would be the tiebreaker.

I lead in average, and I'm tied for the lead in homers.

DJ lead in RBIs, and is tied for the lead in homers.

So, in effect, we each lead in one category and are tied for the lead in another.

So if average is the tiebreaker, how would I not be the winner, since I lead in the tiebreaker category?

If you want to say that a lead of 17 RBIs is worth more than a lead of .035 in average, fine - I agree that it is - but then you're making RBIs the tiebreaker.

Where do you want to draw the line?

How about a 10 RBI lead vs. .050 in average?

How about a 5 RBI lead vs. .035 in average?

How about a 20 RBI lead vs. .100 in average?

How about any of the thousands of different possibilities?

Give us something definite to go on so it's not simply a judgement call on your part when the month is over.
