50 cents says the Lions get more out of Tate than the Jets do out of Decker. IMO both guys are 1Bs. Decker acting as a true #1 in a poor passing offense could be a train wreck.
Decker might be a 1B or a good #2. Tate is a #3...#2 on a good day.
One guy played against #1 CBs in an offense that threw the ball 420 times.
ETA: Not saying Tate won't be a better fantasy player going forward. Just that Decker is a better football player.
The other guy played against #2 or #3 CBs with a HOF QB in an offense that threw 650+ times.
Now the first guy gets to go against #2 QBs with a solid QB and an offense that (based on what the Saints did) should still throw 600+ times.
And the second guy has to go against #1 CBs with dreck at QB in an offense where the coach has said that they'd like to throw 20 times a game.
IMO Tate >> Decker going forward.
