In 2023, the Cardinals used multiple TE sets on 29.7% of their offensive snaps. It was the 5th most used 12 and 13 combined packages in the NFL.
1 - Falcons - 49.6%
2 - Chiefs - 35.1%
3 - Packers - 33.2%
4 - Jaguars - 31.5%
5 - Cardinals - 29.7%
So while I do agree there is a possibility of an increase in multi TE usage, I don't believe the increase is a large one because we already use them at a high rate compared to the league.
As @BACH said there were 1653 TE snaps last year in total. I would expect that to be over 1700 this year.
Raiman likely only has to play 460 snaps of 1700 to pass 40% (1150 average offensive snaps) with only 2 other TE's taking significant snaps. Seems highly likely to me with no injuries. If Higgins or McBride miss games it looks almost certain.
And it's unlikely many of 12P snaps will have McBride and Higgins on the field. Whereas Reiman is likely to feature with both of them.
