Interesting. I wasn't aware. Thanks for the information. But Garoppolo is also a rookie, so presumably we'd be subtracting half his cap hit. The difference in their 2014 cap hits is about $1M, which over 8 games of 2014 would work out to $500K. So you're saying that the Cowboys could find about $300K in rookie pool cap room for Garoppolo (half of his 2014 cap hit), but we couldn't find about $500K to make room for Martin? The rookie cap pool is based on the number of picks, and given that we cut 3 of our 2014 picks (Halapio, Thomas and Gallon) I would think that we would have that much space within the rookie pool.
Obviously, this is all speculative.
