Quite honestly, I think the bigger thing to solve is to get more plate discipline up and down the lineup. Pitches per at bat are huge. If the lineup collectively can improve in this area, this probably will maximize someone like Pujols rather than who hits right behind him in the lineup. Improvement in in plate discipline is like a force multiplier--everyone improves from this. It creates more opportunities by virtue of what happens in front of Pujols. It makes the issue of who hits directly behind Pujols myopic.
I also think the Cubs have more talent than most teams in the division but it's one that severely lacks discipline and cohesion. This is an area of lost/hidden production. At the very least, it's hard to tell what the talent level is because they often play so stupidly.
But back to my original point, I think more of you need to see this in a more wholistic way. One way to protect Pujols is to increase the scenarios where he comes up with 2 guys on base vs. one guy on base and plate discipline is the biggest way to do that. I would even go as far as to suggest that getting mroe guys on base in front of Pujols protects Pujols more than who hits behind him.
