I need help with my Flex this week (1 Viewer)

I have two Flexes in this league I have Gronkowski in my tight end position and I need two of these three in my to flex spots .

Jared Cook, Vernon Davis, and Tyler Lockett.

I need two of those three. I'm thinking that I want to play 3 tight ends but am I crazy in a PPR League I just picked Tyler Lockett up off waivers.  but I feel like  running with Davis and Jared Cook would be a great play.  Is that crazy and does anyone agree or do they think I should throw Tyler Lockett in for one of those?

I think it is an easy decision:

1. Cook and Davis

2. If Reed plays, Cook and Lockett

Thanks for the help on mine ...

it seems crazy, but you're not crazy in this situation. 

Start the 3 TE's ... Lockett is too risky.
