1) If Iraola leaves, can Chanot step into the holding role (I think he could, and should, if we have another CB option)
I think he should if we have another legit CB option. Like Brillant-quality or better. Chanot is just too good aerially to not have back at CB.
2) Is Lampard or Pirlo more vital to our success (I say Lampard)
I personally think Pirlo is more vital to our success. I know he did not have a good game yesterday, but he opens so much up.
3) Someone will be sold this offseason. Does losing Matarrita or Chanot hurt us more?
I don't think either of them will be sold this offseason. I think Mata has one more year here and Chanot hasn't played enough yet.
4) Do we buy Steven Mendoza?
I would, he's been playing very well lately.
5) Do we go into 2017 with RJ Allen as our starting RB?
I think so, I don't think we need to go out and get a RB (except for depth-purposes)
6) With impending departures, do we stay with a 4-3-3 next season? If Lampard is gone, does a 4-2-3-1 make more sense?
I think we'll stay with a 4-3-3 base, but there may be some variations to it as we've seen PV do from time to time this season. It will be interesting to see what impact departures will have on our formation, but also how the arrivals will impact our formation.
