Actually what Flores practiced on Tua was not tough love, but tough hate.
Tua got hurt a few times, or had a few tough moments, but still wanted to play, instead of Flores doing what most coaches do, and allow him to play, grow, and either sink or swim, rather then have someone else starting...No love for Tua there.
Flores tried to find a way to keep Fitz, and, Brissett as starters, tried to bring in Watson, told Tua he was probably going to lose his starting status, and might be gone before he even proved himself in his 2nd season...No type of love for Tua there.
In Tua's 1st season, the OC was there because he was more familiar with Fitz, and what he can do, who created an offense that worked better for Fitz then Tua, then in year 2 promoted two coaches with little to no experience at being an OC on the most crucial season of Tua's career....No love for there.
Sorry Fitz, I know you went to Harvard and all, but you may need to go back to trying to figure out what love actually means. If Tua had actually gotten tough love, Flores would have allowed him (Tua) to dig himself out of the Broncos and Raiders games, and if he failed, might have been a little tough on him, but not as far to destroy his confidence. If it had been tough love, Flores would have told his 1st OC to create an offense where Tua would best benefit, then hold him to high level, and expect him to grow and succeed quickly. If it was tough love, in his 2nd year, he would found an experienced OC that could help Tua grow quickly, and then put him through an intense bunch of camps, while never, ever talking about getting rid of him for anyone else.
The key in Tough love, is the word Love, meaning going far and beyond to get the best from him, but just going about it far more hard-nosed.
