1) Brooks wanted to wear #8 last year, but had to switch because of special teams, at least that's my memory
2) I don't think there's a ton to glean from the practices since they are experimenting and installing a lot of stuff.
3) individually, it's tough to know who's doing well and looking good, but people who looked good to me were:
Register - very smooth and fast, looks like a good option on jet sweeps, similar to D Jones a couple years ago.
Huff Bros - Julian was making some big hits, Jacob had an amazing pick
Green - was pretty darn calm and collected, handled the rush well and bought time to find a dump off target, looked to be very accurate despite pressure
Rallis - made a bunch of plays, seemed to be in the backfield a lot and has some good edge moves
Ray Dixon - looks to have filled out and was much more noticeable than in the past
Ayinde - didn't notice the safeties a ton, but their open field tackling was excellent, Kunle had some nice tackles in space
Rhoda - looks to be very solid, made some great throws, looks poised, a very nice depth option
WRs - I still saw too many drops, but Carter and Still made some great grabs
