Each year, we like to run a series of posts called "90-in-90." The idea is that we'll take a look at every player on the roster, from the very bottom to the top and break them down a few ways. This roster will certainly change, and some days we'll have more than one so it's not exactly 90 players in 90 days. At this point, it's a name we're keeping around for street cred.

The 2014 NFL Draft saw the San Francisco 49ers drafted a trio of players with ACL injuries. They selected offensive guard Brandon Thomas in the fourth round, cornerback Keith Reaser in the fifth round, and fullback Trey Millard in the seventh round.

Reaser tore his ACL last fall, but had to get a second surgery in February when the cadaver graft he used was rejected by his body. He got a graft from his patellar tendon on the second surgery, and essentially re-started his rehab. Reaser likely would have opened training camp on the NFI list if he had only dealt with the fall surgery. The additional surgery likely was enough to end his 2014 season before it begins. He was placed on the NFI list last Thursday. This mens he can take part in meetings and the like, but he is not allowed to practice.

Prior to his ACL injury, Reaser was a speedy corner, supposedly running a 4.32 40 at one point a year ago. I went through some scouting reports, linked below, and both NFL.com and Draft Insider mentioned that "long speed" was a weakness for him. Given that he ran a 4.32 40, I suppose they could be focusing on when he has to run even further down the field. Or maybe it's more connected to just being able to run around on the field if a play gets extended a while. I'm not really sure what would cause someone to lack long speed when they ran a quick 40. Any thoughts? Here's what Field Yates (ESPN guy, former scout, also former SB Nation guy) had to say:

@ninersnation I think of long speed as guys who don't accelerate well but make up for it later. To me, 4.32 is damn fast no matter what. — Field Yates (@FieldYates) July 21, 2014

Expected 2014 impact:

There is almost no chance he is on the roster this season. He could have a miraculous ACL comeback, but given that it was a second surgery on the same injury, I don't see how he isn't on the NFI list all season. In reality, it's more a question of his potential 2015 impact. The 49ers have a lot of options at cornerback this year, but they also have several potential free agents. Chris Culliver and Chris Cook are competing for the starting job outside opposite Tramaine Brock. Both are free agents after this season. Dontae Johnson could work his way into the mix in 2015, and Kenneth Acker will potentially get some opportunities. That could create all kinds of competition for the spot opposite Tramaine Brock

Odds of making the roster:

He'll spend the season on the NFI list. If he fully rehabs the ACL, he has a great shot of earning a roster spot next year.
