Grant Cohn: It's make-or-break time for ‘bubble' players on 49ers' preseason roster
First order of business for the 49ers during tonight's preseason game against the Chargers: Don't play important players. The season starts a week from Sunday. Keep the starters healthy.
Second order of business: Make a list of the 45 best players on the roster, the players who definitely will make the team. These are the players the 49ers do not need to scrutinize in this game.
The box to the right my choices for the best 45 players on the roster, in no particular order.
Third order of business: Of the remaining 45 players on the 90-man roster, make a list of the guys who have legitimate chances to win one of the final eight spots on the 53-man roster. These are the 'bubble players' — the players the 49ers need to evaluate most in this game.
Here's my list of bubble players, in no particular order. And here's where they stand before tonight's game.
1. Matt Barkley, QB. Barkley is playing to prove the 49ers should keep him as the third quarterback. If they keep him, his $1.6 million salary for 2017 becomes guaranteed. That's a lot of money to pay a No. 3 QB. If Barkley doesn't play particularly well in this game, the Niners can cut him and feel confident no other team will sign him. If the Niners need Barkley later in the season, they can bring him back at a reduced rate.
2. Raheem Mostert, RB. You probably hadn't heard of Mostert before this year — he has played for five teams during his two-season career. But during this preseason, he has been the Niners' leading rusher (115 rushing yards), third-leading receiver (104 receiving yards) and starting kick returner. If the Niners cut him, another team almost certainly would sign him — especially if he plays well against the Chargers. Mostert has a good chance to make the Niners' final roster.
3. Joe Williams, RB. The Niners drafted Williams in the fourth round this year presumably to be the No. 2 running back. But Mostert and Matt Breida seem to have passed Williams on the depth chart, so Williams would be the No. 4 running back if he makes the team. Typically when a team keeps a fourth running back, that player is a key special-teams contributor, which Williams is not. That doesn't bode well for him. But, the Niners could keep Williams and make him one of their seven inactive players on game days, so they don't have to worry about having a backup who doesn't play special teams. Williams will need to play well against the Chargers to convince the Niners to make this accommodation for him.
4. Tim Hightower, RB. When the offseason began, Hightower seemed like a probable candidate to make the team, because he was only the running back on the roster who had played for Kyle Shanahan. Hightower's experience in Shanahan's running game gave him an edge. But he hurt his knee during training camp, and in the preseason he has negative 1 rushing yards. If the Niners cut him, they probably could bring him back later if they need him. It's doubtful another team would sign him.
5. Garrett Celek, TE. After trading Vance McDonald to the Steelers, the Niners have just two tight ends who definitely will make the team — George Kittle and Logan Paulsen. Two is not enough. If one were to get hurt during a game, the Niners no longer could use any of their plays featuring two tight ends. So, the Niners need a third tight end, and Celek is the favorite to win that position. He has been playing with the starters during the preseason and he's a good blocker, which is extremely important in Shanahan's run-first offense.
6. Cole Hikutini, TE. The undrafted rookie caught a lot of passes during training camp. But the Niners haven't thrown him any passes yet during the preseason games. If he gets shut out again during tonight's game, he probably will end up on the 49ers practice squad.
7. Kendrick Bourne, WR. This undrafted rookie has been the 49ers' second-leading receiver, and the NFL's 11th-leading receiver during the preseason. He seems good enough to make an NFL roster. If the Niners cut him, another team may sign him. Are the Niners willing to risk losing him? They might have to keep him if he has a big game against the Chargers.
8. Victor Bolden Jr., WR. Another undrafted rookie. Bolden won't make the team based on his ability to play wide receiver — he hasn't caught a pass in the preseason. But he has returned a kickoff 104 yards for a touchdown. Would the 49ers keep Bolden just to return kicks? That depends on how he plays tonight.
9. John Theus, OL. Theus is the 49ers' backup left tackle, which is an important position. But, the Niners already have three offensive tackles who probably will make the team — Joe Staley, Trent Brown and Garry Gilliam. Will the Niners keep a fourth offensive tackle?
