My closest Schultz comparison, TBH, is Neal. Neal was great at scoring goals when combine with Geno and a good LW. He was a big time scorer and getting those goals were certainly important. That said, there was a lot not to like about Neal. He was boneheaded at times, temperamental, and could easily get off his game and when he was off...he was off. But overall, you still liked his goal scoring ability.
I see Schultz in the same light, when you need that offensive minded PMD or PPQB, he could provide that and provide it well. But when he wasn't brining that, there was a lot not to like about that. Then there were obviously some frustrations surrounding some defensive lapses.
So like Neal, with Schultz you have to take the good when its good and take the bad when it's bad. "Better" or "Worse" is all relevant. This board has a hard enough time looking at the big picture regarding anything so I guess the only way to do it would be to count the single instances of good and the single instances of bad and seeing which glass is more full. *spoiler, the good glass is luke warm milk that's been sitting for a day and the bad is a well whiskey straight from your local corner dive bar.*
