I don't really get the point of this argument, especially when I see names like Aiken, Reed (you trolling? Probably, knowing the OP), Marlon Brown. And then there's horrendous examples, like Steve Smith Sr (who had two straight 1,000 yard seasons when Cam first got into the league, btw. This wasn't some career revival in Baltimore).
When looking at guys like Aiken and Brown, they were products of opportunity and volume. In 2013, Brown was a featured aspect of the offense, and as such, he put up mediocre numbers. Then, in 2014 and 2015, still with the Ravens, he dropped into obscurity. No, he did not drop off because he went to another team. Look at Aiken- in 2015, he literally saw 83 targets in 8 games to close out the season, as opposed to just over 40 in the first 8 games. What happens in those final 8 games? He gets over 600 yards. And then a lot of us were pretty hyped for what he could do with Joe in 2016... and then he does absolutely nothing.
I think Mike Wallace is a pretty poor comparison because he did great in Pitt, and then played with two noodle armed quarterbacks. Although, I'd argue that being in Miami was great for his development because he got much better in the short and intermediate game. I mean, came to Baltimore as THE guy and had a quarterback with an arm. We can't really glean anything meaningful because he's on IR in Phili right now.
Maclin posted career worst numbers in Baltimore, so that is one person you definitely do not want to use to support your argument.
Jacoby stayed the course and was pretty much a mediocre receiver in Houston and in Baltimore.
Really, the best recent examples we have are gonna be Torrey falling off a cliff, Jensen having a pretty poor first season with the Bucs, KO making two Pro Bowls and a first team All-Pro, Rick Wagner pretty much being as consistent as he was in Baltimore, Boldin dropping off in Baltimore, but having a resurgence in SF, Watson in the same boat.
So what am I saying? There's really not a lot to gain from this argument because most of these guys either stayed the course or never had another chance after Baltimore. Pretty dumb argument, honestly.
