Two weeks later, after a nine-tackle performance against San Francisco and seven tackles in Thursday's 24-23 win over Tennessee at the Metrodome, the talk now is not only that he has made the roster, but that he is pushing to be the starting outside linebacker when the Vikings open the regular season at Detroit a week from Sunday.
Bishop is a player who believes that practices are vital to the success of a player, but it's what you do when the lights are bright and the game is on that is more indicative of his style and his ability.
"I'm an instinctive guy, that's kind of my strength," Bishop said. "Practice is just preparation for the game. It's about doing it in the game."
Seeing his outlook change in the span of five days isn't anything new for Bishop. A starting inside linebacker in the Packers' 3-4 defense prior to his injury, he was expecting to be competing for that job in Green Bay this preseason, before he was unceremoniously dumped by the Packers after the draft. Going from a player who couldn't be on the field to someone who may have a leg up on the starting job, the Green Bay experience has changed his outlook toward the game.
"Talking about how quickly things can change, I know all about that," Bishop said. "That's why I really don't put too much emphasis on one thing or another because I know how quick things can change. I'm really just grateful to be back healthy and playing again."
Vikings coach Leslie Frazier has been impressed with what he has seen during the last two games, which was a far cry from training camp, when the best that reporters could get from the head coach when asked about Bishop was a shrug and the acknowledgement that he couldn't make a decision on him until he got on the field. After two strong games, they have something meaningful to look at.
"I thought Desmond did a good job," Frazier said. "He was flying around. It was good to see him get out there. He's struggled with injuries over the last year or so, so to see him come out and compete the way he did and put some good tape out there the last two weeks. He's really come on, so that's really encouraging. We're looking forward to watching the tape and evaluating him more."
There will be concerns about whether Bishop will be able to stay healthy, but he has learned a respect for the game that he might not have had prior to the injury and, after being robbed of a year of his NFL life, he's happy to have it finally over with and getting back to doing what he loves to do.
"Besides the scar, I don't have any residual anything," Bishop said. "It was very difficult going through the treatment and rehabbing and not knowing, having that doubt of not knowing if it's going to hold up if you get into a jam. I missed the season and all of the offseason. It was tough, but I'm just grateful to be in the position to be healthy enough to play. I don't take it for granted anymore — I don't take the game for granted, I don't take plays for granted. I just enjoy it."
Not only did head athletic trainer Eric Sugarman and his staff come out on the field, but the EMTs came rushing out on the field with the vehicle to take him off the field. Olsen was surrounded by 10 people and placed onto a backboard after laying motionless for several minutes on the Metrodome turf.
Fortunately, Olsen was in the locker room walking around and chatting up teammates following the game. He was diagnosed with a concussion and no other serious injury.
In an ironic twist, the Vikings' medical staff had just gone through a training procedure with the Hennepin County Medical Center earlier this week at Winter Park to deal with just this kind of incident and it came into play a day later.
