Yikes--There's some good ones there! Sturgis, Hines and Gillislee we'll obviously miss BIG time--the last two, it should be noted, were WAY under-utilized until this season, and Hines I believe CONTINUES to be used much less than we could be getting from him...all he ever DOES is BREAK OUT when called on, and (for example) GILLY'S difficulties of late might well have been (and, in the time left, might still BE) lessened by opening up that offense with Hines' greater use.
The thing about that list is that it's greatest losses appear on offense--where we have a lot of promising replacements coming in, some here and more (hopefully, assuming we KEEP them) "on-the-way"...Moreover, let's face it: there NEED to be "wholesale changes" on offense--those named-above aside, it's NOT as if we could be a much WORSE offense next year!
