“Everybody evaluates their own situation as far as playing this game,” Reid said to The Chronicle. “I’ve evaluated mine and I’ve decided I still want to play.”

Reid, 23, a 2013 first-round pick, said he might seek out more medical advice, but he intends to play in 2015. He has been a full participant in the team’s offseason program.

“There is a doctor that I’m looking further into and I may end up going to see,” Reid said. “Like I said, right now I’ve evaluated my situation and I feel comfortable playing.”

So Reid is the clear favorite. It’s unfortunate, but considering the way he plays and what he’s dealt with, the chances that he’ll still be in the NFL as a player in a few years seem very slim.

NaVorro Bowman

Bowman didn’t suffer a standard ACL tear on that awful play in Seattle. The team is saying all the right things about where he currently stands in his recovery, but what if he’s a step slower? Would Bowman be OK with being an average middle linebacker? When I heard whispers that someone would be leaving the team a couple months back, Bowman was the first player who came to my mind (it ended up being Willis).

Vernon Davis 49ersVernon Davis

Anthony Davis spoke of being in a “white fog” after his concussion last year, and Vernon Davis played like he was stuck in a fog of his own from Week 2 on. Vernon’s problems were mostly back-related, but a hit from Kam Chancellor concussed the 49ers tight end in Dec. 2012, and he suffered another one in 2013 against Carolina when Mike Mitchell drove his head into the Candlestick turf. It would seem that a guy with so many off-the-field interests would want to keep his brain relatively intact, but Vernon seems to have a renewed passion for the game now that Jim Tomsula has replaced Harbaugh, so we’ll see.

Daniel Kilgore

The center suffered a concussion in 2012 and hasn’t fully recovered from a nasty leg fracture sustained last season in Denver.

Joe Staley

He had a concussion in 2011:

Staley said he’s had previous concussions, but “never like that.”

“It was the second one that knocked me out,” Staley said. “The first play, I was fine. I played normal.”

Staley then sustained another concussion 10 months later, in Oct. 2012 against the Cardinals. He’ll be 31 at the start of this season and he’s already made a decent amount of money in his career. However, he may be one of the old school guys who doesn’t really worry about concussions all that much. It seems like the guys who are retiring due to head trauma concerns are on the younger side.

We can probably assume the next retiree won’t be Alex Boone, since Darnell Dockett already asked Boone that very question.

Added Dockett: “With all the battles me and Boone had, today was our first day speaking. It was kind of awkward. We passed each other like seven times before we spoke. I asked him if he was retiring. He said, ‘No.’ So we’re good.

Then again, it’s Boone, so who knows.
