Just some observations, based on people's comments on this board and a bit from a public domain Podcast on CF.
QB - a true open competition, probably starting wit Becht. Kohl is the fan favorite, but most "in the know" comments seem to think Becht is 1 for now.
RB - really a Committee at this point. Harris seems to draw least pub of the 5 and Norton and Sanders the most.
TE - Again, it seems to be a group of prospects. There was a picture of Brahmer catching a pass I saw. He absolutely looked the part. Well muscled, long (I looked for him as a WR 1st), and hands that just enveloped the ball. Kohler came to mind, but more physical looking.
WR - everyone seems high on Higgins. Ngoyi has kind of got the Gaines legendary status from a year ago. Returners need to step up or someone needs to step in.
OLine - I am tempted to say same old same old. Someone posted here(?) or on CF that Simmons was running with the 2's. Hopefully because someone better has been performing. Assuming Hufford and Miller are constants, and Clanton truly cross trains his linemen, the other 3 likely come from Bonifas, Petersen, Maro, Neal, Akinshilo, Treiber, Pauls, and Hasert, with maybe a heretofore unknown walkon thrown in.
This will be an interesting, evolving, and youthful offense.
