Dynasty Value of Hunter Henry

so i just had the Henry owner offer me him+Rashaad Mathews for Duke Johnson, I have Olsen/Clay so looking ahead to next year Henry is prob a nice fit on my roster. Im not to high on mathews though and dont know if i can afford to get rid of Duke. my other Rbs are Cook,McCoy,RoJo,Blount,Ivory,Martin,Conner. Im actually pretty thin on WR also since i just took over this team so i have alot of guys im high on but are prob more WR2s, Anderson,Goodwin,Richardson,Gallup®,T.Smith®,Coutee®,Samuel,Dez,Britt
