You can't be serious
Swaim has 1 TD in his career..... Brate has 20
Brate has played on a team that has used him. Swaim played behind a guy who is a HOF TE. I mean, who's the one here who is not being serious? But more to the point, and really this is what you need to think about here, how good of a blocker is Brate? Is he head and shoulders better because I have not really seen that. Now, I will be honest and say that I have not seen him play much, only a few time actually, but that's the real question here. Do you see Brate as a guy who the Cowboys are going to change their Offense to facilitate? That answer is no. We are not going to change how we do stuff because of him so what you are really paying for is another guy who is going to come to Dallas and gets 4 to 5 targets a game (before we signed Cooper). In this Offense, he is always going to be the 4th or 5th option and lets be real here, how often does Dak get to the 4th option in his read? How often do we even get time to find the 3rd read in the Redzone, which is what we are talking about here because Brate is not a downfield threat.
So where do you see Brate as better? Swaim has a better catch percentage, he has better average yard per catch, he has more average receptions per game, he has better yards per touch so I'm guessing that it has to be in the blocking because in the passing game, Brate is not better.
