Good Lord. The hip was not a factor as to play him or not. The hip injury was a factor on the type of player he would be this year because it completely wipped out all off-season strength/conditioning which resulted in Tua not being at his normal (pre-injury condition)physical readiness. Ok now keep up here his is 100% healed and there is no increased risk for re-injury.So you are saying that Flores replaced a decent QB coming off a good game on a team that was .500 with a rookie QB knowing that his hip would be a negative factor in his play?? Again, if this was the case, Flores should be fired.
Now the first big decision comes into play before the season. Option 1 Flo is not comfortable with his level of play in his current level of strength and conditioning. If Flo felt this way then he could have carried an extra QB. This would allow Tua to just focus on strength/conditioning which is good but has two downsides. First we waste a roster spot on a 3rd QB and second Tua loses reps in practice. Second option is just accept that this will be the level of strength/conditioning Tua will have to play this season at. Well Flo picked this option. Again at this point the hip doesn't matter, its healed and Flo has just accepted where Tua is at from a strength/conditioning stand point.
Now the second decision was when Flo opted to start Tua. This is were nobody can know for sure other then Flo. But again the hip is not a factor anymore. Maybe The was great in practice? Nobody but can really know why.
Now this is my personal opinion/theory on why he went with Tua. I think Flo wants to win now, but also has a long term plan set out from the beginning. I believe Flo thought he could go with Tua and win the same amount of games by changing the Offensive philosophy a little. Basically Fitz would give us more downfield offensive, but he is Fitzmagic/Fitztragic for a reason. I think he went with Tua play conservative as the D was playing great. Win the same amount of games and get Tua live reps. Whether he was right or wrong is up to debate.
