No HI insiders can give us the what we know synopsis? This is me pathetically groveling for info right now.
My guess is that Santos is not our #1 choice at LB. He's probably a backup option to some of the other guys. There's no guarantee that any of the other guys will come on board, thus we want to keep Santos around in case... which is a delicate see-saw effect... you don't want the kid to feel like you don't want him, but then you don't want to take him unless the others shy away or commit elsewhere... so you have to keep him interested and wanting to play for us without committing or knowing he's being slow played as a "second best option".
Some sites say he's 6' 193 lb 4.6 speed
Some say he's 6' 205 lb 4.5 speed
Either way... he is on the smaller side for a DI lb... Phillip Dillard was 240lbs (which was a little heavy, but was a big difference in size). Does that mean he's too small for us? No, because Bo likes the smaller, faster lb for his Defensive system. He can run more disguised schemes with smaller backs who disguise themselves as LB or S, or CB, and who blitz at any time.
We know Santos wants N... we know the coaches "haven't been there" when he's called, we know historically speaking, that when the coaches REALLY want someone bad they do a good job of contacting that person often... so it makes me think that the coaches must think they are close to landing some of the others like maybe a Dexter Moody, or a Keith Lewis, or a Rahim Cassell, or a Denzel Perryman, or even an Anthony Wallace...
