Were there a lot of scabs playing in the '87 strike season in the NFL?

just wondering as Reggie White put up 21 sacks in 12 games (=28 in 16) and Jerry Rice had 22 TD (which is ~29 in 16 games). Both would have been official records if they continued the production, but I thought that maybe some teams might have had scab players and the competition would have been lower.
