My pre-training camp best guess at the 53:
QB (2)
Locks: Lamar, Huntley
Bubble: Thompson
Longshots: Fagnano, Pavia
QB seems easy enough unless Thompson does enough that they want to keep him as the emergency 3rd QB on gameday rosters.
RB (4)
Locks: Henry
Near Locks: Hill, Ali, Randall
Longshots: McMillan, Tau-Tolliver
RB doesn't need much explaining. Barring a surprise this group is pretty much set already.
TE (4)
Locks: Andrews
Near Locks: Smythe, Hibner, Cuevas
Longshots: Pezza, Scott
TE much like RB doesn't need much explaining. Again barring a significant underperformance by the rookies, this group is basically locked already.
WR (6)
Locks: Flowers, Bateman
Near Locks: Walker, Lane, Sarratt
Bubble: Wester
Longshots: Wade, Guillory, Johnson, Smith Jr, Braham Jr
Feels harsh to call Wade a longshot but he is. Wester is only really on the bubble because we've added some other potential return options this offseason, but i'd still expect him to win the WR6 and starting PR job.
OL (9)
Locks: Stanley, Simpson, Ioane, Rosengarten
Near Locks: Jones Jr, Vinson, Pocic, Pinter
Bubble: Vorhees, Gwyn, Beertsen, Bullock, Pounds
Longshots: Lichtenhan, Penning, Dawkins
Seems like we're almost locked on 8 of the 9/10 OL right now. Vorhees would be my favourite right now to be last man on. Pinter still feels like a near lock for the 53 to me even with the Pocic signing.
DL (7)
Locks: Madubuike, Jones, Campbell, Jenkins
Bubble: Peebles, Washington, Benny, Okoye
Longshots: Olajiga, Wilson Jr, Graves
Could definitely see them only keep 6 DL here. Hard to choose who the last one off would be though - Peebles in year 2 and who showed promising flashes as a rookie feels hard to leave off, Washington has underperformed his contract but hard to argue he's not good in the rotation, Benny has the traits and trust with the coaching staff that it feels tough to project him missing out. Which is why i've ballparked 7 DL for now. Would not surprise me though if they kept 6 DL and opted for an extra EDGE or LB.
EDGE (4)
Locks: Hendrickson, Green, Robinson, Young
Bubble: Isaac, Rucker
Longshots: Burke
Feels pretty straightforward. Only real question is whether Isaac can earn himself a 53 man roster spot or not as a 5th EDGE vs someone at another position.
LB (4)
Locks: Smith, Buchanan, Simpson
Bubble: Higgins
Longshots: Williford, DeLuca, Jones
Again feels like a light position but we always seem to be able to find guys at LB. Right now though hard to pick more than the 4 guys who were there last year.
DB (10)
Locks: Hamilton, Starks, Wiggins, Humphrey, Hawkins, Awuzie
Near Locks: Tampa
Bubble: Jackson, Rivers, Martin, Kone, Longerbeam, Oruwariye, Wallace
Longshots: Robinson, McDoom, Webb Jr, Robinson, Walters
The bottom of the 53 at DB feels so hard to predict. Jackson feels like the easy one because of his special teams prowess. Rivers feels tough to leave off because of the draft pick status. Which for me would leave Martin vs Kone for the final DB spot right now but would potentially leave you light at safety which is where K'Von Wallace might fit in and sneak on at the end.
For me the questions going into camp right now for last spots on are:
OL10 vs DL7 vs EDGE5 (Isaac) vs LB5 vs DB11 for 1 spot on the roster
and then also the competition for the last "guaranteed" positional spots at various positions too:
OL9 - 1 of: Vorhees vs Gwyn vs Beertsen vs Bullock vs Pounds
DL6 - 2 of: Peebles, Washington, Benny, Okoye
DB10 - 3 of: Jackson, Rivers, Martin, Kone, Longerbeam, Oruwariye, Wallace
