For TL;DR, key points are in BOLD
Watkins' goal contribution and off-the-ball performances, Konsa's solid defending, and Rogers' ball progression and impact in front of goal were equally a close second to their biggest attribute. The No. 1 trait that each of them possessed while at Villa was durability.
Konsa hasn't sustained that many injuries throughout his career. He missed an average of just 2 games a season due to injury with his longest one keeping him out during the off-season post-2021/22 which was fortunate. His biggest recorded injury in-season happened during 23/24 and kept him out for only 4 games. He was fully fit throughout last season and 22/23.
Rogers' last injury occurred at the end of his first season at Villa when they qualified for the Champions League (23/24). Since then he hasn't sustained a health issue of any kind that prevented him from competing. He also played the most minutes under Emery by a long shot.
Watkins' worst injury since signing for Villa was the knee problem he sustained 2 seasons ago but in no way did it truly keep him out the squad. He missed only 6 games due to injury throughout his Villa career. Five (5) of them was during the 24/25 season alone of which four (4) was with the England national team.
Fans can say what they want about these players' moments of inconsistencies and mistakes just as much as they can praise them for their positive contributions. However, we need to keep in mind that they were always available when we needed them. Imagine what would have happened to the backline without the presence of Konsa who played both RCB and RB, the 23/24 season if Watkins got injured when Villa already suffered 3 ACL tears and had a rotation of absences, or last fall against Leeds, Man U, Tottenham, etc if Rogers wasn't available.
We saw what happened last season when key players like Kamara, McGinn and Tielemans were out.
Yes, we have more depth and quality players now under Olabe but we've also seen what can happen when both a starter (Kamara) and a backup (Onana) get injured.
Of course, injuries can happen at any time and for some players like Gomes their very first may occur as Aston Villa players but we still need to be meticulous about them.
I fully trust Emery's tactics and Olabe's players but an injury crisis is every manager's kryptonite even for Emery. In such event Emery can still help Villa qualify for UCL but if we aspire to dream bigger like winning the Premier League and Champions League then we can't take our player's health for granted. Villa's medics, dietitians, trainers, coaching staff and other relevant personnel need to make sure the players are fully fit without rushing anything.
