normally i am all for better QB, RB and WR, and go easy on TE, but in this case, i don't think upgrade from Hillis to DMC is enough to cover the downgrade from Gate to Kendrick
you going from semi-stud RB to almost-stud RB, but this almost-stud RB have bad injury record, and you never know when it will hit you. upside is when DMC is good, he is a monster.
and you going from top stud TE to waiver TE, you can even find better TE than Kendrick in some league.
unless you have huge crash on DMC, otherwise, save Hillis and Gate, they should get more score than DMC+waiver TE
