Do I make a QB move having Watson v. Jax this week?

So this is my matchup this week. I am strongly considering picking up a QB to replace Watson this week. Picking up someone would mean dropping Corey Davis.(I could do Allison, but frankly I would rather have a WR2/3 in GB than the WR1 in Tenn.)

Available for this week are Baker, Flacco, Eli and Mitch.

Do I pick one up now or do I wait until Friday and see how DJ and DT do and make the move then if they put up big points?

You’re in an extremely strong position to win this contest IMO. Def a QB deficit between Watson and Winston but my guess is you win no matter. Who is on the waiver and who must you drop to acquire him?

Mentioned in the post - would be dropping Corey Davis and available is Baker, Flacco, Eli and Trubisky.
