First top 100 (actually top 300 if you load the other pages) was released by Scout, with a lot of other updated and expanded rankings. There are currently 33 5*s, and the 4*s extend out to the 250th ranked player (meaning currently players ranked 251-300 are 3*s).
There are several interesting rankings/listings, but here are some players of interest and a few observations/comments.
Braden #40 OT, 3*
Stacey #33 OG, 3*
Kiel #1 QB, 5*, 17th overall
Pike #3 QB, 5*, 25th overall - slight UM lean maybe? hopefully?
Fuller #9 QB, 4*, 163rd overall - I guess somebody likes him as a QB
Garmon #11 RB, 65th overall - he is listed as the RB most likely to commit to Mich over on Touch the Banner.com (is that Magnus's site right?)
Burbridge #11 WR, 84th overall - I had once heard he was a MSU lean, is that still presumed true?
Stanford #16 WR, 106th overall
Thompson #5 TE, 4*, 137th overall (Yeah Ron! If you look at my previous posts, I had him on my wish list even when he was getting no recruiting hype, so you can imagine how happy I am to see him get this ranking. Go Blue Ron!) - strong Mich lean
Funchess #6 TE, 146 overall - maybe a Mich lean?
McNamara #7 TE, 165 overall - presumed OSU lean, from SD area
Peat #2 OT, 5*, 3rd overall - would be a huge get - both literally and figuratively
Murphy #8 OT, 34th overall
Diamond #9 OT, 4*, 40th overall - presumed Mich lean
Simmons #2 OG, 5*, 30th overall - his mentor is a former Mich OL, story is on front of Michigan's Rivals page, but I'm not an insider
Wormley #13 DE, 4*, 112th overall - Mich lean
Shittu #7 DT, 50th overall
Day #9 DT, 4*, 64th overall - grew up Mich fan right? presumed Mich lean
O'Brien #14 DT, 4*, 131st overall - I actually expected him to be higher than Day, but I guess we stand a better shot at Day any way right? Personally, I would be quite happy if we could get both of them - still a Tenn lean though?
Ross #2 MLB, 4*, 72nd overall - would love to get several of these LBs
Ringer #8 MLB, 4*, 206th overall - April 15th-ish, is that the date we hopefully ring in Ringer (it's late, I'm allowed bad puns)
Odenigbo #2 OLB, 58th overall - I didn't realize he was this highly regarded, although he has already been selected to the Under Armour All American game for next year
RJS #7 OLB, 4*, 105th overall
Darby #2 CB, 40th overall - some sources list him as RB
Richardson #8 CB, 4*, 139th overall
Reeves #10 CB, 177th overall
Stefon Diggs is listed as #2 at SAFETY! 5*, I had never heard of him being projected as a safety before (actually I about soiled myself when I didn't see him listed in the section on WRs interested in us) - 16th overall
Wilson #10 S, 4*, 151st overall - probably the safety we have best shot at?
Interestingly, Brionte Dunn is a 5* while Warren Ball is a 4*. These are both RBs committed to OSU and we are trying to steal Dunn because i think Ball was OSU's first choice (definitely committed first and I think was offered first). Perhaps still a long shot, but how awesome would it be to steal a 5* from OSU. Remember, Dunn committed b/f the issues with Tressel were made known, so maybe he will reconsider a little. Anyone with more info on the topic please feel free to clarify where we stand with Dunn. Both are top 100 overall.
OSU is actually doing well with 2 5*s already and looking good with at least 1 more (DE Adolphus Washington). It will be interesting to see how the situation with Tressel affects recruiting. All currently committed recruits committed before the story broke.
***EDITED*** Wormley has been updated to a Michigan lean as several posters below mention that OSU may not be as strong of a threat as I had feared.
