I feel like this is taking off prematurely. I don't recall Lester ever saying that he was moving to or developing an offense that is heavy in its' use of 12 personnel.
I started a thread a month or so ago talking about how that was his primary set at Elmhurst. I don't believe he's come out and said anything about having intentions to do it here. I could be 100% wrong. I haven't been paying close attention this week, but, the only article with Lester I've seen from the Post Standard was a couple weeks back where he stated that our current roster supports 10/11 or 20/21 personnel.
Regardless, it doesn't matter, personnel grouping doesn't affect formations as much as one might think. And, it would most likely be a package in the early years as opposed to a base.
This is all just conjecture on my part.
