Now that I think about it, I really don't know. OP put up a good question.
I honestly think scheme comes into effect and it might be somewhat of an effect for Torrey. I think we could've saw a much better Torrey Smith had he played in an offense that didn't feature so many crossing/shallow patterns because his stiff hips and trouble with his breaks, he just didn't run those routes consistently well. I feel like we could have gotten a lot more in another offense from him. Same case can be made for Wallace but Torrey didn't get to show as much as he could. Let's not forget, in the 2013 season Torrey Smith led the league in receiving yards with 623 and we completely burning guys as the de facto #1 WR with virtually no help at the other receiver positions, running game, and to include poor QB play that was contributed largely by lack of an OL and running game. Team knew Torrey was the only capable receiver but he completely destroying coverage and defensive backs. His 2013 season could've been a big year for him, I'm talking potentially 1,300 Yards and 6+TDs had he gotten the help he needed and that's in an offense that's not the best fit for him. I always felt that Torrey catches way too much slack here, his 2013 season is impressive given the circumstances and maybe...just maybe his 2014 season was simply a down year comparable to the seasons we've seen from guys like Alshon Jeffery, Brandon Marshall, and others.
