Re: the secondary. Kelly is a classic "fill each position" guy when you look at general recruiting overview. Last Year, like almost all transition years, was tough on him. Still, he recruited four players for DB [Wood, Badger, Spencer...forgive me young man, I forget your last name at the moment...old age, and Roback]. One transferred for understandable reasons; one decided with our depth at safety, to take his mission; one transferred to try to play QB elsewhere.
This left us with good vets, but only Lo Wood as a youngster. Kelly, not being blind, assessed this and decided to go a little heavy on DBs this year. He got commitments from five, most of whom seemed versatile. Not to overdue it, he stopped there. For next year, he will go back to position-filling. And he knows that he has Badger returning as a full-grown man, physically and personally. Counting Badger as ONE, I look for Kelly to shoot for three more---and beyond that only if he assesses his current crop as weak.
Kelly has done this same reasoning/planning everywhere on the roster I believe. He let NT go this year, in my opinion, due to his confidence in Nix, and apparently Stockton, as well as poor choices "out there" available. He may want to double-fill there next year. Look also at the combination of the O+D lines. He should have recruited 5+3=8. Hegarty, Martin, Hanratty, Carrico, Springmann, Lynch, Hounshell, Tuitt. Note that he has recruited versatility in that group, where three could easily be seen flipping one way or the other. Last year he did what he could in a difficult recruiting situation: James, Lombard, Nichols, Schwenke, Utopu, Nix, and with fingers crossed, Heggie]. Still he fell one short, and with Matt James' death, two. Thus the press to get at least five potential O-linemen this year.
He was heavy on wide receivers last year [TJ, Bennett, Daniel, Austin]. This year:two [Daniels, Atkinson]. Should add up to six [three positions times two] for the two years. This is the year-to-year best strategy. Once you've got "coverage", you can add supermen at the last minute as they become available. I think the man's a classic strategist.
