From the layout of the roster it looks like we have a few versatille spots which we are counting on for Depth
RB/FB (If we are going to run the I) - Taysom is clearly a role player/backup as running the I we should have 5 RB/FB on the roster
WR Juwan Johnson (normally you would have 7 WRs on the roster so Juwan would count here)
TE We really should be carrying 4 with the I so if we are flexing Juwan so Taysom/Juwaan are expected for depth here as well.
With all the flex roles having 3 QBs not counting Taysom is fine. Particularly since 2 are PS eligible if we need to make game day adjustments.
