Rate my team please (full pt ppr)

My league went heavy on QBs (one guy has three!!), and took them very early, so I did not have much left to choose from in the later rounds (although I did get to grab good rb/wr value). I grabbed Mariota, and Trubisky/Darnold/Bortles/Keenum/Bradford are still available. Any thoughts on potentially stashing one of the available (since streaming seems tougher to do if Mariota doesn’t pan out) or swapping Mariota altogether? I would be dropping Lockett if I chose to stash a QB.

Thanks all!
