Slater is just a fast guy. Patterson is a true wide receiver. It all (as it always does) comes down to how he can track the long ball and adjust to where it is. Some can, some just can’t. Not sure Patterson has ever had a QB who didn’t flat out suck at throwing deep either.
I just looked it up a few days ago...here are CP's career receving stats and the QB's he played with:

2014: 16 games, 7 starts, 67 targets, 33 rec, 384 yards, and 1 TD. (QB's: Bridgewater, Cassell, and Ponder)
2015: 16 games, 1 start, 2 targets, 2 rec, 10 yards, and 0 TD's. (Bridgewater)
2016: 16 games, 8 starts, 70 targets, 52 rec, 453 yards, and 2 TD's. (Bradford and Hill)
