Anyone else surprised about the depth of this LB group in training camp so far?

It seems like the LBs are the spiciest position battle to this point. Based on several reports from camp, Perryman isn't locked in as a starter yet and is being pushed by To'oTo'o for the MIKE spot. Obviously Perryman should still be the starter, but it's insane to me that it's even in question. And I don't think it's because Perryman has been bad, it's just that To'oTo'o has come on strong very quickly. The emergence of Cashman has also been out of nowhere. He's made a lot big plays, but can he play consistently every down? Harris has also apparently been flying around the field and is looking better than ever.

Overall it has been a very pleasant surprise to have several guys step up in the LB room. Perhaps this is the effect of having a former star LB as the head coach?
