The surefire cuts are perhaps the easiest to predict.
Without spending too much time looking at the 49ers' 90-man roster, most of us should be able to find a good chunk of players who have almost zero chance of making the roster in 2014. Many were brought in as mere competition during camp or insurance for any injury in the preseason, etc.
Colton Schmidt, P
This is perhaps the easiest assumption to make in this entire slideshow, so let's get it out of the way first.
Behind incumbent punter Andy Lee, Colton Schmidt has virtually no chance of making the roster in 2014. The only way this happens is if Lee suffers any sort of injury during the first three weeks of the preseason.
We won't rule out that possibility—if anything, we hope against it—but Schmidt's release will be one of the easier decisions the 49ers' brass makes leading up to the regular season.
D.J. Campbell, S
Two-year pro D.J. Campbell was brought on in early 2014 to a reserve/future contract, per Matt Barrows of The Sacramento Bee.
Having spent the prior two years split between the Carolina Panthers and Miami Dolphins, he does have a limited amount of experience under his belt—nine regular season games to be exact.
Campbell is buried on San Francisco's depth chart, however, and would have to thwart other veterans such as Eric Reid, Antoine Bethea, Craig Dahl, C.J. Spillman and Bubba Ventrone. That's not going to happen.
But as David Fucillo of Niners Nation points out, Campbell is eligible for the practice squad and has a better chance of making the roster a year from now given some of the contractual situations with the aforementioned players.
James McCray, S
Another UDFA signed by the 49ers after the 2014 draft was safety James "L.J." McCray out of Catawba.
McCray missed the entire 2011 season with an injury, so there are some durability concerns remaining, but he did showcase some skill on special teams, per Steve Muench of Scout's Inc., (via Bill Williamson of ESPN.com)—perhaps justifying why the 49ers signed him.
But like many UDFAs, McCray has almost an insurmountable chance of making the roster in 2014.
While he is eligible for the practice squad, much of that decision will hinder on how he performs during the preseason and whether or not San Francisco's coaches feel as if he can contribute in some way in a developmental aspect.
As such, don't expect to see him on the roster this season.
Chase Thomas, OLB
Outside linebacker Chase Thomas initially signed with the New Orleans Saints as an UDFA prior to the 2013 season, then he made his way through a number of teams before signing with the 49ers in May.
A Stanford prospect, Thomas has familiarity with coaches Jim Harbaugh and Vic Fangio. Fangio has worked plenty with him, per Eric Branch of SF Gate, but Thomas understands that nothing is guaranteed.
Thomas is buried deep on San Francisco's outside linebacker depth chart behind Aldon Smith, Ahmad Brooks, Corey Lemonier, Dan Skuta and Aaron Lynch. The only way for Thomas to make the team is if Smith's pending suspension, in combination with injuries, shakes up the chart.
Fortunately for Thomas, he is still eligible for the practice squad—a likely destination considering the circumstances.
Kaleb Ramsey, DT
Defensive tackle Kaleb Ramsey has a fair share of injury problems.
This is evidenced by the fact that he spent six years at Boston College before eventually being drafted by San Francisco in 2014 in the seventh round.
At his best, Ramsey is a big, physical specimen, but his injury history is something that certainly thwarts any lofty expectations placed upon him.
Thus, it should have been no surprise that he started camp on the team's physically unable to play (PUP) list per Barrows.
Placing him on the PUP list instead of the non-football injury list suggests that this is something Ramsey suffered in camp opposed to a collegiate injury.
Considering his history, this isn't a good sign, and this argument is also made by Fucillo.
Ramsey's future will be entirely contingent on his recovery. If he is able to make it back from this injury, the likeliest of destinations will be on the practice squad. But if the injury lingers to any significant point, the 49ers will probably just part ways with him.
Kevin Greene, TE
The battle for San Francisco's third tight end slot heated up a bit when the 49ers inked UDFA Kevin Greene out of USC last May.
Greene, 6'4" and 255 pounds, saw action in 37 games for the Trojans, including nine games in 2013. While at USC, Greene spent time at tight end and defensive end/linebacker, where he registered 11 tackles, two sacks, two forced fumbles and one fumble recovery, per 49ers.com.
While Greene does have some likable attributes, it is hard to overlook the plethora of players ahead of him in the competition for the No. 3 slot. With Vernon Davis and Vance McDonald securing the Nos 1 and 2 positions, the final choice comes from a competition between Garrett Celek, Derek Carrier, Asante Cleveland and Greene.
Those are a lot of bodies to overcome.
It is feasible that Greene makes the practice squad, but the 49ers may have simply signed him to put some pressure on the remaining cast of tight end backups.
Greene won't be on the roster by the end of August.
David Reed, WR
Had wide receiver David Reed been signed prior to the 2013 season, he may have had an outside chance to crack San Francisco's roster. We remember just how thin the 49ers were at the position heading into that season.
Now, San Francisco's receiving crop is stacked, which leaves almost zero room for fringe players such as Reed to earn a roster spot.
Reed was signed to a reserve/future contract back in January when San Francisco's receiving situation was still much in doubt. With some of the offseason additions, Reed's future looks about as grim with the 49ers as possible.
Reed does have some experience in the return game, totaling 24 kick returns for the Indianapolis Colts last season. Perhaps he has a shot at making the roster if LaMichael James' injury affects his return longer than expected.
Even so, that possibility is a long shot at best. Reed is ineligible for the practice squad, so the 49ers will likely just part ways with him when they see fit.
