As long the veteran ( enter the name you want ) play in an elite league during the lock-out I dont really see a problem. Since veteran take more time to get in shape.
But I dont think any team will sign players before the new CBA is signed. So these veterans might get less money since they will be 1 precious year older.
I think what the poster meant was with the progress rookies/young players will make in the AHL or wherever, will a veteran be necessary? (ex: Plekanec and Hossa and Ryder(?) make strides in the AHL and make Kovalev unnecesary when hockey resumes.
I think a player like Kovalev who is an incredible talent can help anyone. However, lesser-talented veteran players may lose out when hockey resumes and younger players have that extra development under their belts
