With the 2018 NFL season drawing closer, there's still plenty of business to be done off the field. In just over one month, the 2018 NFL draft will take place - and it's shaping up to be one of the most exciting in years. That's because there are a lot of teams looking to take a quarterback and early reports suggest that up to six signal-callers could be selected in the first round. Sam Darnold and Josh Allen are expected to be picked first, before the likes of Josh Rosen and Baker Mayfield. But it's not all about the draft. In fact, there are two big-name free agent quarterbacks that are desperate to find another team. Those two are Johnny Manziel and Colin Kaepernick. It's fair to say that both have had rocky NFL careers so far and each became a free agent ahead of the 2017 season.Manziel was released by the Cleveland Browns, while Kaepernick opted out of a contract with the San Francisco 49ers - and neither have played since. As both are now looking for a way back into the league, they're often mentioned in the same comparison - despite being out of the NFL for very different reasons. And those comparisons have been going for far too long. Well, that's according to Manziel. He posted a series of tweets on Saturday that suggests he's grown tired of the thought. As well as making his personal viewpoint very clear, "Johnny Football" also paid respect to Kaepernick and what he's fighting for - wishing him all the best in the future. "This will probably cause an uproar, but I’m tired of the @Kaepernick7 vs myself comparisons and anger," he wrote, beginning a series of tweets. Check them out below. 

It's fair to say Manziel has made his feelings clear - and you can't really blame him, especially as he's trying so hard to get a second chance at football. 

And he knows that to do so, he'll need to separate himself from all the controversy that surrounds his peers - as well as himself.   

But with over four months until the 2018 NFL pre-season begins, there is plenty of time for both Manziel and Kaepernick to get back into the league. 

However, it's not clear if any team would be willing to take them ahead of a draft prospect. Many of the teams that need a starting QB are going to try and get their business done in the draft. 

That could mean that even if one, or both free agents do get signed, they may be forced to play as a back-up.
