Technically, Sweat is the starter at LB and has been most of the season. Even when Mata came back from injury, Sweat got the nod.
Yeah but Mata was still working towards full fitness. No doubt that if he is fully fit, Sweat is back on the bench.
Ha! Not sure I will even give you "technically correct" on that one.
However, your point does reveal some interesting information.
Matarrita started the first 6 games at left back. Since then, Sweat has started 14 of 15 games while Matarrita has mostly been unavailable due to injuries and national team duty.
Matarrita has been available for 3 games since he first sat for an injury.
- In our 2-1 win over Philadelphia, he came off the bench, but it was for Camargo at LW.
- In our 2-0 win over the Red Fools three weeks later, he again came off the bench, again at LW, this time for Wallace.
- In our 3-1 win over Minnesota, Matarrita started at LB before being subbed out early with a broken foot; Sweat started at RB.
The interesting observation is that when Matarrita was coming off the bench as he returned to fitness, he came on at LW, not LB. Plus, while he started at LB in his last game (Minnesota), that was the game where Allen and White were punished for not showing up on time. So, it's not clear who Patrick would have started at LB. Indeed, I seem to recall that there was some talk that Matarrita would start over Wallace at LW before the shakeup.
So, I think it is possible that with a fully healthy lineup, Sweat would get some starts at LB with Matarrita ahead on the wing. That said, I do think that Matarrita would have kept the job at LB without the injuries, and I think ultimately the first choice lineup will be Matarrita and Wallace on the left side, assuming we can ever get both of them healthy.
As an aside, the only other guy to start at LB for us this season is RJ Allen against RSL in that ridiculous lineup that Coach V used to throw an easy game.
