Yeah, super early. Injuries will happen, just put us off to a slow start. Hopefully they'll settle down!
Playing a 4 at SS isn't a very good idea. At least he's only an e14, but you're adding 13 points to the opponent BA on your pitcher's card (vis-a-vis playing a 2). Mathematically it's not a great idea. That said, if he hits *enough* you can over come that. Hence the need for ratings that evaluate the math of the D versus the extra hitting.
By my ratings Lowrie is the 22nd best SS v RHp (not taking injuries into account). That's in the average park. He's slightly behind Quintanilla, but slightly ahead of the no bat/good glove Ryan. At home he's going to be better than that (closer to 15), but on the road, in a pitcher's park or a non-LH park he's going to drop. A better bargain guy might be Pennington or E Cabrera.
You can't look at just the bat of your 7 mil SS versus Lowrie, but the whole package of what it does to your team makeup. Your pitching might be the same, but you might have a cheap DH instead, for example, you might choose to play LOWRIE at DH and have someone who can actually pick the ball up at SS!
You're right in saying it's all tradeoffs, but I'm pretty sure you're underestimating the value of a glove at SS and also, the logic behind TSF.
You're going to hit, that's for sure (at least when you have your guys on the field) and in this league with all the hitter's parks, that might work. Whether you can hold leads in the late innings will depend on how well Hal matches up your pen to the hitters they are facing. You also have a TON of injury guys and only 2 players on your entire roster that have a max 3 game injury. You'll have to be fortunate in that regard also I would think becase your bench isn't especially deep and is also injury prone. For example, it wouldn't be surprising to see Lowrie and Furcal out at the same time and then you'll have Hal picking a SS for you.
Interestingly enough, you spent more than the average on pitching. You were able to do this by taking a bunch of injury prone hitters.
Time will tell.
