If the Rams could sign Garcon and Bennett that would be a good fit and it would boost the Rams offense.
Garcon is older, but he is a superb WR with good speed, good hands, and good route running who knows McVay's offense.
Bennett is a very good TE who blocks well and is a good receiver. Not spectacular at either, he is proficient at both and is a huge target.
I have to think that they won't break the bank, although they won't be cheap ($7 - 8 mil each?)
