This is all obviously very subject to change. We haven't even seen a game yet, but I'll take a shot at what I think and hope the roster looks like come week 1.
Hanie fills the Curtis Painter role of last year. He'll come in and play some garbage time in preseason games. There's no need for 3 QB's when we have so much talent at other positions.
Running Back (3):
The first 2 are obvious locks. Allen gets the 3rd spot due to his ST prowess. Rainey is a great player, but what's the sense in keeping a guy that's never going to play unless Rice gets injured. For being renowned for his return abilities, his numbers were pretty abysmal last year. 15 yards per KR and 1.5 yards per PR. That's not enough to make the team.
There isn't much to say here. Leach will be the lead blocker and Juice will help out in the passing game. He'll learn under Leach for a year or two.
Wide Receiver (6):
The first 4 are locks, and Reed is very close to it due to his ST contributions. The 6th spot comes down to Streeter, Williams, and Mellette. I picked Streeter because of his red zone ability. Without Pitta, we don't have that true red zone threat. Streeter can play sparingly and hopefully continue to develop. Mellette has had a very up and down camp against the 3rd team D. He could be one of Ozzie typical "IR" stashes. LaQuan is the same every year. He shows well in practice but can't translate to games. Marlon Brown is an IR candidate while he fully recovers from his torn ACL.
Tight End (3):
This was the toughest to predict. I really wanted to go with Furst, but the team loves Bajema's blocking ability. With two potentially below average blockers in Dickson and Shiancoe, I think they go with the blocking specialist. This is the one position I think could completely change in the next few weeks.
Offensive Line (8):
In: Bryant McKinnie, Kelechi Osemele, Gino Gradkowski, Marshal Yanda, Michael Oher, Rick Wagner, AQ Shipley, Jah Reid; Out: Ramon Harewood, Jack Cornell, Joe Unga, Rogers Gaines, Jordan Devey, Antoine McClain, Reggie Stephens, Ryan Jensen (likely IR)
There's not too much disparity here. Our 5 starters are locks as are out 3 backups. Harewood could push his way onto the roster, but for now, I'll leave him off. Joe Unga is a guy that could surprise as he's been regularly playing with the 2nd team in camp. There are a few PS options but none that really compete for the roster.
Defensive Line (7):
This is another position that I think is pretty much settled. Despite Cody's poor performance, he's cheap depth at NT. Pericak could push for the roster, but I ultimately think he winds up on the PS and makes a very strong push for the roster next year.
Inside Linebacker (4):
The 4 that make it have all split time with the first team D. Carr and Hall could make a very strong push, but it's hard to keep 10 LB's (I'm picking 5 at OLB). McClain still hasn't been cleared so I doubt he has a shot at the original 53 man roster.
Outside Linebacker (5):
This is another position that I think the names I picked are guaranteed barring special circumstances. Hamilton has performed very well, but keeping 10 LB's will be very difficult with having 2 FB's on the team. He's one to continually keep an eye on, though.
The top 4 are guaranteed, while spots 5 and 6 are up for grabs. The Ravens love Johnson's veteran presence and play on the field. His legs are back under him after a long hiatus from the game, and I'll give him the spot. Anthony gets a spot now that Jackson has been suspended. Moe Lee was a standout at OTA's, but has struggled since the pads came on in camp.
The first 3 are locks and Brown is picking up right where he left off. Levine could make a push but I don't expect much. Thompson is suspended so he doesn't factor into the discussion until week 5.
Special Teams (3):
They have no competition, so they're in.
